PCM-40 pcm channel analyzer 2 automatic test sequences you can produce automatic test sequences by combining several test configurations together from the range of setups which you have stored. all of the measurement functions included in the PCM-40 along with any variations in test variables, parameters and tolerance limits, can be used for this in any order required. the sequence can be programmed to stop if an incorrect result is obtained or before each dif - ferent measurement task. monitoring digital paths in through mode or via high-impedance taps for long-term monitoring of 2 mb/s paths, the circuit can be looped-through the PCM-40 transparently or tapped via a high impedance monitor point. if the power supply fails during loop-through measurements , the signal path is not interrupted. the following measurements can be performed: ? frame monitoring with fas errors recorded as histograms ? level, frequency and coder level monitoring including audio monitoring in a selected channel ? recording of byte changes in the selected frame or data channel ? signaling status display for individual chan - nels quality monitoring in an idle channel facilities for monitoring the quality of pcm systems which do not use crc frames are lim - ited to monitoring the frame alignment signals. the PCM-40 can, however, perform a loop- back or end-to-end measurement to itu-t g.821 in an idle channel. the instrument transmits a test pattern which it then evalu - ates. the results can be shown as a table or as an error histogram. PCM-40 as an automated measuring system when testing pcm multiplexers, the pcs-40 channel selector connects up to 30 analog tx and rx channels sequentially to the PCM-40 analog test ports. the pcs-40 channel selector allows return loss and longitudinal conversion loss measurements on individual vf channels using the built-in bridges. also test needing d.c. loop holding circuit or feeding bridge are possible. the result is a flexible and powerful test system well suited to production, installa - tion and maintenance of 2 mb/s multiplexers. te fall-of in gain can be clearly seen. te blue trace was recorded on commissioning the system, the red trace at a later date. te diff reslt function de - termines the diference between the two traces. te zoom function and cursors allow every detail to be examined. a test confguration (setup) includes all test and inter - face parameters required to perform a measurement. te setup name is used to relate the setup to a particu - lar device under test. errors in the idle channel shown with their times of occurrence. sporadic faults can thus be easily seen and matched in time to possible sources of interference. automatic sequential connection of up to 30 analog tx and rx ports of a pcm mux equipment to the PCM-40 channel analyzer. 30 channel automatic sequential weighted noise mea - surement PCM-40 pcs-40 channel selector pcm mux tx tx rx rx ch x ch x ch 1 to 30 ch 1 to 30
