Specifications describe the instrument's warranted performance over the temperature range 0 to 55 C (except where noted). Supplemental characteristics are intended to provide information useful in applying the instrument, by giving typical but non-warranted performance parameters. These are denoted as "typical," "nominal," or "approximate."
Agilent 8757D scalar network analyzer
The Agilent 8757D has four independent display channels that process the signals from the Agilent 85037 series precision detectors, 85025 and 85026 detectors, and the 85027 series directional bridges for logarithmic display, in single channel or ratio mode. Three (optionally four) detector inputs are provided. AUX voltage The rear panel BNC input ADC IN can be measured and displayed in volts (-10 to +10 volts). Typical maximum error is 60 mV. Color settings Up to 8 operator-selectable colors are available for LCD attributes, such as the grid, measurement traces, and labels. Sweep time The minimum sweep time depends on the number of traces displayed and the number of points selected.

LCD Display 640 (horizontal) x 480 (vertical) resolution A display is considered faulty if: * A complete row or column of "stuck" or "dark" pixels. * More than six "stuck on" pixels (but not more than three green) or more than 0.002% of the total pixels are within the LCD specifications. * More than twelve "dark" pixels (but no more than seven of the same color) or more than 0.004% of the total pixels are within the LCD specifications. * Two or more consecutive "stuck on" pixels or three or more consecutive "dark" pixel (but no more than one set of two consecutive dark pixels) "Stuck on" of "dark" pixels less than 6.5 mm apart (excluding consecutive pixels) Display modes All analyzer display channels can display any one of the detector inputs or any ratio combination of detector inputs. Log magnitude dBm: single channel power measurement dB: relative power measurement (ratio or relative to trace memory) SWR Relative measurements (normalized or ratio measurements) can be displayed in SWR. Channels 1 and 2 only: 401 points or fewer
Averaging 2, 4, 8, 16, 32, 64, 128, or 256 successive traces can be averaged. Smoothing Provides a linear moving average of adjacent data points. The smoothing aperture defines the trace width (number of data points) to be averaged, and ranges from 0.1% to 20% of the trace width. Normalization Traces are stored and normalized with the highest resolution, independent of display scale/division or offset. With adaptive normalization on the Agilent 8757D, calibration data is interpolated when the frequency span is decreased. Limit lines Limit lines facilitate quick pass/fail decisions. Limits can be any combination of flat or sloped lines or single points up to 12 segments. They are only available for channels 1 and 2, for traces with 401 points or fewer, and can be stored in save/recall registers 1 through 4.

Internal save/recall registers
Up to 9 complete front panel states may be saved or recalled. If the source (Agilent PSG, 8360 or 8370 series) is connected to the 8757 system interface, the front panel states of both the network analyzer and source are saved. Registers 1 through 4 store the instrument state and the memory traces for channels 1 and 2. The memory traces for channels 3 and 4 are not stored. Registers 5 through 9 only store the instrument state.

Modulator drive The modulator drive output of the 8757 scalar analyzer provides the circuitry to drive the 8340/50/60/70 series synthesized sweepers and the Agilent 11665B modulator. Modulation drive may be turned on and off via the front panel or GPIB. In the "off" state, the modulator drive signal turns the 11665B fully on for minimum insertion loss. The 8360 and 8370 synthesized sweepers have the capability of modulating signals, so an external modulator such as the 11665B is not necessary when using the 8360/70 series. Frequency: 27,778 Hz 12 Hz Symmetry: 50% 1% Stop sweep Used with the PSG, 8360 and 8370 series when controlled by the 8757 system interface to stop the sweep at band crossings and at the end of sweep. ADC in An input connector for auxiliary voltage input in the -10 to +10 volt range. This voltage can be displayed (in volts) on any channel. Control 1 and control 2 These connectors provide digital output signals (TTL open-collector) as a user convenience for driving other peripheral equipment in a GPIB controlled system. Video outputs Used to drive an external color monitor that has the following characteristics: 8757D with LCD monitor (VGA input on the analyzer's rear panel) * VGA compatible 8757D with CRT monitor (RGB inputs on the analyzer's rear panel) * Red, green, and blue (RGB) BNC inputs, sync on green * 75 ohm input impedance * 26.5 kHz horizontal scan rate * 60 Hz vertical refresh rate * 1 V p-p (typically 0.7 V = white; 0 V = black; -0.3 V = sync)

System interface
The Agilent 8757 system interface is a dedicated GPIB port used exclusively by the 8757 to control and extract information from a swept source, a digital plotter, and a printer. Compatible swept sources The following swept sources are specifically made to complement the 8757 system. With them, the 8757 is able to display start, stop, and marker frequencies, save and recall front panel states of both the sweeper and the scalar analyzer, preset both instruments simultaneously, and alternately sweep two different frequency or power ranges and display both simultaneously: * Agilent PSG1 signal generators (Option 007) * Agilent 8360 series synthesized sweeper * Agilent 8370 series synthesized sweeper Printers For a list of compatible printers, consult our printer-compatibility guide Web page. Its URL location is http://www.agilent.com/find/pcg. Or go to www.agilent.com and use keyword search printer guide. Internal plotter/printer buffer The GPIB buffer speeds measurements by returning the control to the analyzer while outputting data to a plotter or printer. Output two channels (401 points each) of information to the buffer in typically less than 5 seconds.
Note: In order to use the currently available printers a GP-IB to parallel port adapter is needed. Adapters are available from Intelligent Interfaces. Please see their website at http://www.intelligentinterfaces.com.

System accuracy
Transmission measurement accuracy
Transmission loss or gain measurements are made relative to a 0 dB reference point established at calibration. Transmission measurement uncertainty = dynamic power accuracy + mismatch uncertainty Dynamic power accuracy is the measurement uncertainty due to the change in power level between calibration and the measurement. Mismatch uncertainty is the uncertainty due to reflections in the measurement setup. The frequency response errors of the source, detectors, bridge, and power splitter are removed via calibration. Transmission measurement uncertainty examples Assumptions: * Measurement frequency = 10 GHz * DUT input/output SWR = 1.5 * Ratio measurement
Absolute power measurement accuracy
This specification is useful for determining the accuracy of power measurements in dBm when using the Agilent 85037 series precision detectors or the 85025 series detectors in DC mode. Absolute power uncertainty = absolute power accuracy at 50 MHz + frequency response + mismatch uncertainty Absolute power measurement uncertainty examples Assumptions: * Measurement frequency = 10 GHz * DUT input/output SWR = 1.5

Precision detector vs. power sensor absolute power measurement accuracy
Accuracy terms differ depending on the test equipment used to make absolute power measurements. The following table simplifies and compares the accuracy terms of an Agilent 8757 system (using an 85037 series precision detector) and a power meter (using a power sensor). A measurement accuracy example is also provided.
Scalar terms Absolute power accuracy at 50 MHz Equivalent power meter/sensor terms Power reference uncertainty Instrument linearity Zero set Noise Sensor calibration factor uncertainty Mismatch
Reflection measurement accuracy
Uncertainties due to calibration error and the frequency response of the source, detectors, and bridges are removed via open/short averaging. The remaining uncertainties are primarily the sum of directivity uncertainty, effective source match uncertainty, and dynamic power accuracy. As shown in the graphs below, directivity is the dominant error term when measuring small reflected signals (high return loss) and source match is dominant when measuring large reflected signals (low return loss).

Detectors
Agilent 85037 series precision detectors (AC/DC) The 85037 series precision detectors are designed specifically for operation with the Agilent 8757D scalar network analyzer and are not compatible with the 8757A/E, 8756, or 8755 scalar network analyzers. These detectors may be used in either AC or DC detection modes. For improved power measurement accuracy versus frequency, each 85037 series precision detector includes detector specific frequency response data, stored in an internal EEPROM, which is automatically read by the 8757D. When used in conjunction with the 8757D's internal power calibrator (Option 002), these detectors provide the maximum absolute power measurement accuracy. Agilent 85025 and 85026 series detectors (AC/DC) The 85025 and 85026 series detectors are designed specifically for operation with the Agilent 8757 scalar network analyzer and are not compatible with either the 8756 or the 8755. The 85025/26 detectors may be used in either AC or DC detection modes.

Agilent 11665B modulator
Note: This product is no longer available. The 11665B modulator is only necessary when using the 8340/8341 series synthesizer.
Agilent 11613B calibrator
The 11613B is a dedicated transfer standard for calibration of the 8757. The 11613B provides the standard, a 27.778 kHz source, and a series of precision attenuators. The calibrator includes software (3.5-inch format) that operates on an HP 9000 series 200 or 300 computer, the BASIC operating system (BASIC 3.0 or higher), or an external controller with HP BASIC for Windows 7.0 or higher. The software verifies (and adjusts if necessary) the internal calibration parameters stored in the nonvolatile memory of the 8757. All 8757 detector inputs can be calibrated in a matter of minutes. Recalibration of the 11613B is recommended every two years. Memory requirement: 0.5 Mbyte Outputs The 5-pin cable (1.22 m) mates with the detector inputs of the 8757. The lines in this cable transfer the squarewave signal to the 8757, provide power for the 11613B (from the 8757 supply), and program the 11613B's internal attenuators. Dimensions: 40 H x 185 W x 203 mm D (1.5 x 7.3 x 8.0 in) Cable length: 1.22 m (48 in) Weight: Net: 0.91 kg (2 lbs), Shipping: 2.3 kg (5 lbs)
The 11665B modulates test signals with the 27.8 kHz modulation drive signal from the scalar network analyzer. Frequency range: 15 MHz to 18 GHz Insertion loss and return loss
