4-19. X3 GAIN ACCURACY
ThIS test measures the output voltage at the Main Out-
put and at the X3 output to determine the gain. The gain
at 10kHz is specified to be 3 ± 1070.
Equipment Required:
C. Connect the 50 Ohm Feedthrough to the 3314A's
MaIO Output. Connect the 5000 Feedthrough Termina-
tion to the 3314A's X3 Output
D. Set the digital voltmeter to measure > 3.5VRMS
and then measure and record the voltage from the Main
Output (VI).
F. Compute the gam error using the following for-
mula'
E. Set the digital voltmeter to measure > 1O.6VRMS
and then measure and record the voltage from the X3
Output (V2).
