2.2.3
Measuring Frequency Using Counter
Frequencies are measured using the counter function. Use the CAL signal of the analyzer as input signal.
The counter function measures the signal frequency at the marker with high accuracy.
The value of an amplitude indicates the amplitude at the marker point.
The maximum resolution possible for the counter function display is 1 Hz. As you increase the resolution,
you will have to increase the gate time to compensate.
CAUTION:
1.
The counter function may not work normally if the span is greater than 1 GHz or the difference between the
marker and the noise level is 25 dB or less.
2.
The signal track mode cannot be used with this function.
Power on
1.
Turn the analyzer power on.
Initialization
This resets the current settings to the factory defaults or user-defined presets.
2.
Press SHIFT and CONFIG(PRESET).
This sets the analyzer to its presets values.
Connecting calibration signal
Connect the calibration signal used in the measurement.
3.
Attach the N-BNC adapter to the INPUT connector on the front panel.
4.
Connect the Input cable from the CAL OUT connector to the INPUT connector.
Setting the measurement conditions
This changes the analyzer settings so that the input signal is displayed more clearly.
5.
Press FREQ, 3, 0 and MHz.
A center frequency of 30 MHz is set.
6.
Press SPAN, 5, 0 and MHz.
A frequency span of 50 MHz is set.
