Programming Command Guidelines
• Overrun error: A receiver buffer overflows, and received
data is lost. This error is most commonly
caused by too fast communication speed
(Baud Rate). In this case, reduce the
communication speed (Baud Rate).
Programming Guidelines
When you are going to write a test program, refer to the
following guidelines.
• When more than two query commands are sent, the
controller must read the output of each query command from
the Tester. Otherwise, the controller may not be able to read
the output of prior query after the next query is sent to the
Tester.
• To read the measurement results, wait until the
measurement ends. To check the measurement status, read
the
Status Byte Register using the
*STB?
query command
and check the
Data Ready Bit
(Bit 0) and the
Measuring Status Bit
(Bit 1).
• When testing by the Automatic Test mode or the Manual Test
mode, wait until the step of the Test flow ends. To check the
status of the Test flow, send the
TESTs:AUTO:MEASure:SIGNaling:STATe?
query
command when the test mode is the Automatic Test mode, or
send the
TESTs:MANual:SIGNaling:STATe?
query
command when the test mode is the Manual Test mode.
Typical Programming Flow for the Tester
When you write a test program for the Tester, insert the
following steps in your program.
Step 1
Reset the instrument and set the preset settings except for the
setting of serial, GP-IB and Ethernet interface.
< Send Command to the Tester>
*RST
Step 2
Select the W-CDMA application, and display the [Initial] screen
of the W-CDMA system.
