Functional Testing
Frequency Readout Accuracy
Figure 3-2
Procedure
1. Connect the equipment as shown in Figure 3-2. Remember to
connect the 10MHz REF OUT of the analyzer to the 10MHz REF IN
of the synthesized sweeper.
2. Perform the following steps to set up the equipment:
a. Press
INSTRUMENT PRESET on the synthesized sweeper, then set
the controls as follows:
CW, 1.490 GHz
POWER LEVEL, – 10dBm
b. Press System, Power On/Preset, Preset (Factory), Preset on the
analyzer, then wait for the preset routine to finish. Set the
analyzer by pressing the following keys:
Frequency, 1.490 GHz
SPAN, 10 MHz
BW/Avg, Resolution BW Auto Man, 100 kHz
Video BW Auto Man, 30 kHz
CAUTION Use only 75 Ω cables, connectors, or adapters on instruments with 75 Ω
inputs, or damage to connectors will occur.
3. Press
Peak Search on the analyzer to measure the frequency readout
accuracy. If the instrument is functioning correctly, the result in the
active function should be between 1.48991 GHz and 1.49009 GHz.
Record this in the Marker Frequency Readout column in Table 3-2.
4. Press
Span, 100 kHz, BW/Avg, Resolution BW (Man), 1 kHz,
Video BW (Man), 1 kHz.
