Improving Command Processing Speed
SCPI commands should be processed quickly to improve throughput when the commands
are frequently executed (for example, reading out the trace for each measurement).
With the E5052A, the processing time for SCPI commands can be improved by decreasing
the refresh rate of the LCD display.
When measurement results (trace) do need not updating
When the measurement trace does not need to be updated, turn off the update function of
the LCD display. This improves the processing speed of SCPI commands and eliminates
the updating time needed by the screen.
To turn off the update function of the LCD display, use the following command:
•
When measurement results (trace) need updating
The measurement trace can be updated by using following command with the update of the
LCD display turned off.
•
NOTE
The update of the LCD display is off even if you execute this command.
Step 1.
Turn Off the update of the LCD display.
•
Step 2.
Execute all SCPI commands required before measurement, including settings of
measurement conditions.
Step 3.
Perform the measurement.
Step 4.
Execute the commands for reading out or analizing the measurement result. Note that
reading out the result in binary format accelerates data transfer.
Step 5.
Execute the following command to update the LCD display once.
•
NOTE
When the update of the LCD display is off, “Update Off” is displayed in the instrument
status bar.
