Measuring the Signal Frequency Using the Frequency
Counter
The built-in frequency counter allows you to measure the frequency more accu-
rately than measuring it with the marker. The frequency sweep is stopped at the
marker, and the R&S
FSVA/FSV measures the frequency of the signal at the
marker position.
In the following example, the frequency of the generator at 128 MHz is shown by
using the marker.
Prerequisite
In this example, a precise frequency measurement is to be performed. Therefore,
connect the signal generator's "Ref OUT" connector to the analyzer's "Ref IN"
connector.
1. Set the signal analyzer to the default state by pressing the PRESET key.
The R&S
FSVA/FSV is set to its default state.
2. Set the center frequency and the span.
a) Press the FREQ key and enter 128 MHz.
The center frequency of the R&S
FSVA/FSV is set to 128 MHz.
b) Press the SPAN key and enter
1 MHz
.
The frequency span of the R&S
FSVA/FSV is set to 1 MHz.
3. In the "Setup" menu, select "Reference Ext".
4. Activate the marker by pressing the MKR key.
The marker is activated and set to the signal maximum. The level and the fre-
quency of the marker are displayed in the marker field (diagram header or
marker table).
5. Activate the frequency counter by pressing the "Sig Count On/Off" softkey in
the "MKR FUNC" menu.
The result of frequency counting is displayed in the selected resolution in the
marker field.
