Improving Command Processing Speed; When Measurement Results (Trace) Do Need Not Updating; When Measurement Results (Trace) Need Updating - Agilent Technologies E5052A Programmer's Manual

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:
• :DISPlay:ENABle on page 227

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.
• :DISPlay:UPDate:IMMediate on page 261
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.
• :DISPlay:ENABle on page 227
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.
• :DISPlay:UPDate:IMMediate on page 261
NOTE When the update of the LCD display is off, "Update Off" is displayed in the instrument
status bar.
