Application
Frequency counters are usually used as measuring instruments for RF signal frequency measurement.This note shows how to perform frequency measurement with the Handheld signal analyzer MSA500 series with the same accuracy as the frequency counter.
Solution
For accurate frequency measurement in the MSA 500 series, use the marker & peak search function in real time mode.
(SAVE/LOAD F6(PRESET)Preset signal analyzer.)
- OPERATION MODE Select real time mode.
- TRIG F4(SCAN) Select “CONTINUE” to repeat measurement.
- OPERATION MODE Return to Real Time Mode Menu.
-
F2 Go to SUB-MESUREMENT Mode Menu
-
- F3 Select SUB screen OFF.
- F6 Return to Real Time Mode Menu.
- F1 Go to SUB-MESUREMENT Mode Menu. (See (4) for Real Time Mode Menu.)
-
- F1 Select MAIN screen ”SPECTRUM”.
- F6 Return to Real Time Mode Menu.
- SPAN Select the narrowest possible span. HOLD/RUN Measure. MKR Go to Main menu of marker function.
-
- F1 Select marker ”NORMAL”.
- F4 Select ”PEAK SEARCH WHOLE”.
-
F1 Perform “PEAK SEARCH” and read the frequency of the marker.
(*)
Marker accuracy in real time mode is determined by (1) + (2) of
the following specifications.
- Center frequency Accuracy ±0.5ppm ±1dot
- Frequency span Accuracy ±0.1% ±1dot (1dot : (Frequency span)/(500dots))
