Chapter 1 Performance Tests

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

4Sweep 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).

5Record 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.
