The ammeter is shorted for use in subsequent measurements. Input a 1.0VP-P, 100kHz sine wave to SG, and obtain GV from the following formula given TP1 voltage as V1 and TP3 voltage as V2. GV=20LOG (V2/V1) dB For the above GV measurement, given TP3 voltage for 10MHz as V3, FC is obtained from the following formula. FC=20LOG (V3/V2) dB Input a 1.0VP-P staircase wave to SG, and measure differential gain at TP3. APL=10~90% Proceed as for DG, and measure differential phase. Measure the DC voltage difference of each switch status at TP2. Assume VC1=2.1V, VC2=0.7V. Input a 2.0VP-P, 4.43MHz sine wave to SG, and given TP1 voltage as V4 and TP3 voltage as V5, CT is obtained from the following formula. CT = 20LOG (V5/V4) dB Impress an optional DC voltage on TP6 and TP7. Gradually raise from VC1=0V. TP4 voltage when TP7 voltage is output on TP2 is VIH1. Gradually lower from VC1=VCC. TP4 voltage when TP6 voltage is output on TP2 is VIL1. Impress an optional DC voltage on TP6 and TP8. Gradually raise from VC1=0V. TP5 voltage when TP8 voltage is output on TP2 is VIH2. Gradually lower from VC1=VCC. TP5 voltage when TP6 voltage is output on TP2 is VIL2.
