any changes to the UUT or to the measuring receiver settings after you make your
first measurement.
Step 1. Setup the measurement system. See
To measure the RF frequency, you do not need to perform the Power Meter
calibration.
Step 2. Make sure you have selected
Step 3. Adjust the signal generator to the required settings for your test.
Step 4. Press
The default measurement is Frequency Counter with display units in Hz.
Step 5. When the measurement is completed, the measurement result will display.
The PSA can only search for a signal within a maximum center frequency offset:
NOTE
Maximum Searchable Offset = (106 *RBW) or (0.001% of Tuned Frequency)
Step 6. You can adjust measurement settings by pressing
1. To change the tuning mode from
the expected frequency value and unit. The default tuning mode is
Using Manual Tuning mode in the following cases:
a. The SigLo warning indicator on screen when you decrease the signal level.
b. You need to measure the Frequency Error. The Frequency Error is the
c. You need to increase the measurement speed by using a known signal.
You may connect the PSA and the UUT to a common high standard time base.
NOTE
Make sure the time base lock is not used for Frequency Counter measurements.
