Figure 2-6 Frequency Span Readout Accuracy Test Setup
5. Adjust the analyzer center frequency, if necessary, to place the lower
frequency on the second vertical graticule line (one division from the
left-most graticule line).
6. On the analyzer, press Single. Wait for the completion of a new
sweep, then press the following keys:
Peak Search (or Search)
Marker, Delta
Peak Search (or Search)
Next Peak
NOTE The two markers should be on the signals near the second and tenth
vertical graticule lines (the first graticule line is the left-most).
7. If necessary, continue pressing Next Peak until the active marker is
on the right-most signal (2700 MHz).
8. Record the marker delta (∆ Mkr1) frequency reading as Test Record
entry 1 of the performance verification test record.
100 kHz and 100 MHz Frequency Span Readout Accuracy
1. Set the analyzer by pressing the following keys:
FREQUENCY, Start Freq, 10 MHz
Stop Freq, 110 MHz
Sweep, Sweep (Cont)
2. On the synthesized sweeper set the controls as follows:
CW, 100 MHz
