Step 1: Set Up the Test Set

Step 1: Set Up the Test Set

Last updated: January 16, 2009

In this step you initialize the test set and set up general operating conditions.

Initialize the Test Set

Fully Preset the Test Set

It is important to start each production session with the test set in a known state. Sending the *RST command resets all parameters to their default values, ends all measurement processes, and sets all measurement triggers to single.

Clear the Error Queue

At the start of each production session it is useful to clear the error queue so that you know any messages logged are relevant to the current production session.

Programming Example

 
210   OUTPUT Testset;"*RST"
220   OUTPUT Testset;"*CLS"

Set Up General Operating Conditions

Turn Debugger On

The debugger is useful while you are developing code. When it is on, the test set alerts you when you send an incorrect command. You should turn it off once your code is complete.

Set Operating Mode

There are four operating modes available: Active Cell, FDD Test Mode, CW Mode, or Cell Off Mode.

Some cell and connection parameters can not be set unless the operating mode is set to Cell Off.

Set Amplitude Offsets

You can account for path loss in your system by setting amplitude offsets. You can specify up to 20 frequency/amplitude pairs.

Programming Example

 
230   OUTPUT Testset;"SYST:COMM:GPIB:DEB ON"
240   OUTPUT Testset;"CALL:OPER:MODE OFF"
250   OUTPUT Testset;"SYST:CORR:FREQ 2000MHZ"
260   OUTPUT Testset;"SYST:CORR -1"
