Performance Verification Tests
4. Frequency Readout and Marker Frequency Count Accuracy: Agilent E4404B, E4405B,
E4407B, and E4408B
Part 2: Marker Count Accuracy
Perform "Part 1: Frequency Readout Accuracy" before performing this
procedure.
1. Press Preset on the analyzer. Press the Factory Preset softkey, if it is
displayed. Set the analyzer to measure the marker count accuracy by
pressing the following keys:
FREQUENCY, 1.5 GHz
SPAN, 20 MHz
BW/Avg, Res BW, 100 kHz (Man)
Freq Count, Marker Count (On)
Resolution (Man)
2. Press Peak Search (or Search), then wait for a count be taken (it may
take several seconds).
3. Record the counter (Cntr1) frequency reading in the performance
