How to perform measurements in MSRA
mode
The following step-by-step instructions demonstrate how to perform a measurement in
MSRA mode.
How to capture I/Q data in MSRA mode
1. Press the [MODE] key and select the "MSRA" operating mode.
Confirm the message.
2. Select the "Overview" softkey to display the "Overview" for an MSRA measure-
ment.
3. Select the "Input" button to select the input signal source.
4. Select the "Amplitude" button to define the attenuation, reference level or other set-
tings that affect the input signal's amplitude and scaling.
5. Select the "Frequency" button to define the input signal's center frequency.
6. Optionally, select the "Trigger" button and define a trigger for data acquisition, for
example an IQ Power trigger to start capturing data only when a specific power is
exceeded.
7. Select the "Bandwidth" button and define the bandwidth parameters for data acqui-
sition:
● "Sample rate" or "Analysis Bandwidth:" the span of the input signal to be cap-
tured for analysis, or the rate at which samples are captured (both values are
correlated)
● Optionally, if a bandwidth extension (> 160
MHz) is installed, the "Maximum
Bandwidth", depending on whether you require a larger bandwidth or fewer
spurious emissions.
● "Measurement Time:" how long the data is to be captured
● "Record Length": the number of samples to be captured (also defined by sam-
ple rate and measurement time)
8. If necessary, select the "Display Config" button and select other displays (up to a
total of 6) required to control the acquired data.
Arrange them on the display to suit your preferences.
9. Exit the SmartGrid mode.
10. Optionally, stop continuous measurement mode by the Sequencer and perform a
single data acquisition:
a) Select the Sequencer icon ( ) from the toolbar.
b) Set the Sequencer state to "OFF".
c) Press the [RUN SINGLE] key.
