Test 2: Channel 1 Frequency Sensitivity (Agilent 53181A Only)

Assembly-Level Service Guide 1-53

4 Sweep the frequency from 100 kHz to 100 MHz. For Option 060, sweep

frequencies from 100 kHz to 225 MHz.

The Counter should read frequencies from 100 kHz to 100 MHz at an input power

level of ≤ −21.0 dBm (20 mVrms). Option 060 Counters should read frequencies from

100 kHz to 225 MHz at ≤ −9.5 dBm (75 mVrms).

5 Record the actual reading in the Performance Test Record (Test 2, Line 1).

If you are testing a Counter with front-panel terminals (Standard), record the

reading on Line 1 of the Standard portion of the test record.

If you are testing a Counter with rear terminals (Option 060), record the reading on

Line 1 of the Option 060 portion of the test record.

NOTE DO NOT test the front terminals if rear terminals are installed. The front terminal

performance is not specified when the rear terminals are installed.

NOTE The remaining sensitivity procedures are NOT required for Counters that contain

Option 060 Rear Terminals; thus, this completes the sensitivity portion of the

Frequency Performance Test. Go to the Frequency Accuracy Test on page 1-55.
