To prepare for measuring from the capture buffer
When you measure from the time-capture buffer, the analyzer processes the raw input
data stored in the buffer to provide the various types of measurement data available
under the [
Meas Data
] hardkey. Preparing to measure from the capture buffer involves
specifying those measurement parameters that affect how the input data is processed.
1 Initialize the analyzer.
Press [
Preset
][
DO PRESET
].
Press [
Inst Mode
], then press the softkey corresponding to the instrument mode you
want to use.
Press [
CHANNELS 1 2
] (or [
CHANNELS 1 2 4
]) to highlight the number of channels whose
data was stored in the buffer.
If the capture buffer contains input data from four channels, press [
REF CHANS 1 1,3
]to
select the reference channel (or channels).
2 Specify the measurement parameters.
Press [
Freq
], then specify the frequency parameters or time-record length.
If you selected the FFT, order, or correlation instrument mode, press [
Window
], then
specify the windowing parameters.
3 Specify the triggering and averaging parameters.
Press [
Trigger
][
ARM SETUP
], then specify the arming parameters.
If you selected the order instrument mode and want to display phase information, press
[
Trigger
][
EXTERNAL TRIGGER
].
Press [
Avg
], then specify the averaging parameters.
