Test Set Parameters
In addition to the parameters described early in this chapter, there are also parameters that are used to
configure the test set for a sequence. These parameters can be set up from the front panel or by remote
control SCPI commands. For details on how to set up these parameters from the front panel see Chapter
6 , “Front Panel Sequence Setup,” on page 77.
Attenuation
In the test set you can set a mechanical and/or electronic attenuation. The electronic attenuation is set in
the Acquisition setup, but the mechanical attenuation must be set prior to running the Sequence. The
mechanical attenuation is set from the front panel by selecting the
AMPTD Y Scale hardkey and
selecting
Attenuation. The remote control command for attenuation is:
[:SENSe]:LSEQuencer:POWer[:RF]:ATTenuation <rel_ampl>
This command is documented in more detail in the Sequence Analyzer online help (or in pdf format, the
User’s and Programmer’s Reference).
RF inputs and outputs
There are four RF connectors on the left side of the test set’s front panel, which can be configured as
follows:
•
RF Input can be selected as the input port, but not as the output port.
•
RF Output can be selected as the output port, but not as the input port.
•
RF I/O 1 can be selected as the input port, or the output port, or both.
•
RF I/O 2 can be selected as the input port, or the output port, or both.
NOTE It is not possible to have more than one input port at a time, or more than one output port
at a time. However, it is possible to use one of the RF I/O connectors as the input port and
the output port simultaneously.
