To create a waveform using a single, measured trace
You use trace data to generate arbitrary waveforms. You can generate
short or long waveforms. Short waveforms have up to 4096 samples of
complex data or 8192 samples of real data. Long waveforms have more
than 4096 samples of complex or 8192 samples of real data.
There are two ways of generating trace data. You can use measured data
or you can use a computer program (such as MATLAB1) on your
computer to generate trace data. This and the next task show you how to
generate arbitrary waveforms using measured data. Subsequent tasks show
you how to generate arbitrary waveforms using computer-generated data.
The steps below show you how to use a single, measured trace to create a
short arbitrary waveform. See ‘’To create a waveform using multiple,
measured traces’’ to learn how to create long arbitrary waveforms.
1. Initialize the analyzer and select the Vector instrument mode:
Press [
Instrument Mode
], [
receiver
], then press:
89410A: [
input section (0-10 MHz)
].
89441A: [
RF section (0-10 MHz)
].
Press [
Preset
].
Press [
Instrument Mode
], [
Vector
].
2. Connect your signal to the analyzer (this example uses the analyzer’s source to
provide a 1 MHz fixed-sine signal).
Connect the SOURCE output to the CHANNEL 1 input.
Press [
Source
], [
source on
].
3. Select time-domain data.
Press [
Measurement Data], [main time].
4. Start the measurement:
Press [
Meas Restart
].
5. Save the trace data into a data register:
Press [
Save/Recall
], [
save trace
], [
into D1
].
6. Configure the arbitrary source to use your data:
