Improving Command Processing Speed
SCPI commands should be processed in shorter time to improve throughput, when those
commands are frequently executed (for example, reading out trace for each measurement).
With E5061A/E5062A, processing time for SCPI commands can be improved by
decreasing refresh rate of the LCD display.
Measurement results (trace) need not to be updated
When the measurement trace needs not to be updated, turn off the update of the LCD
display. This improves processing speed of SCPI commands and eliminates updating time
of the screen.
To turn off the update of the LCD display, use the following command:
:DISP:ENAB command on page 312
Measurement results (trace) need to be updated
When the measurement trace needs to be updated, processing speed of SCPI commands
can be improved by controlling the update timing of the LCD display:
Step 1. Execute all SCPI commands that are required before measurement, including commands
setting conditions.
Step 2. Turning Off the update of the LCD display.
Step 3. Perform the measurement.
Step 4. Execute the commands for reading out measurement result or analyzing the result. Note
that reading out the result in binary format will accelerate data transfer.
Step 5. Execute the following command to update the LCD display once.
:DISP:UPD command on page 318
Step 6. Return to the step 3.
