1. SENSITIVITY - Channel A

Specification:

15 mV rms, 0-35 MHz (dc coupled)

20Hz-35 MHz (ac coupled)

50 mV rms, 35 MHz-100 MHz

Description: A signal generator with calibrated output is set to the specified 5328 signal sensitivity level and varied over the specified frequency range. The counter must display the correct frequency.

a.10 Hz to 10 MHz

Setup:

(1) DC coupled 10 Hz to 10 MHz

l Set the 5328A to FREQ A, 1 Hz RESOLUTION, SAMPLE RATE fully ccw, Level A to PRESET, DC COUPLING, ATTEN X1, SEP. Rear panel ARM switch should be set to OFF.

. Set the 651B for 15 mV rms. Vary the 651B’s frequency from 10 Hz to 10 MHz and verify that the 5328A displays the proper frequency. Adjust the 5328 LEVEL A control as necessary to achieve a stable display. Mark results on perform- ance test record at the end of these procedures.

(2) AC coupled 20 Hz to 10MHz

l Set the 5328 to AC coupling.

l Set the 651B for 15 mV rms. Vary the 561B’s frequency from 20 Hz to 10 MHz and verify that the counter displays the proper frequency. Adjust the 5328 LEVEL A control as necessary to achieve a stable display. Mark results on per- formance test record at the end of these procedures.
