and 1DQ
Figure 3-7
Procedure
1. Calibrate the tracking generator by pressing System, Alignments,
Align Now, TG. Connect the RF Out to the Input when prompted.
2. 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, 50 MHz
CF Step Auto Man, 500 MHz
SPAN, Zero Span
Source, Amplitude (On), 0 dBm (50 Ω RF Output only)
Source, Amplitude (On), +42.76 dBmV (75 Ω RF Output only)
3. Zero and calibrate the power meter and RF power sensor. Make sure
the power meter is reading out in dBm. Enter the power sensor
5 MHz cal factor into the power meter.
NOTE 75 Ω RF Out only: Zero and calibrate the 75 Ω power sensor.
4. Connect the 100 kHz to 1.5 GHz power sensor to the RF Out on the
analyzer as shown in Figure 3-7.
NOTE 75 Ω RF Out only: Connect the 75 Ω power sensor through an adapter
to the RF Out 75 Ω.
5. Press REL on the power meter. The power meter readout
amplitudes are now relative to the power level at 50 MHz.
6. Set the analyzer center frequency to 100 kHz.
NOTE 75 Ω RF Out only: Set the analyzer center frequency to 1 MHz.
