3 M9347A SCPI Command Reference
Introduction
The M9347A module is a PXIe Dual Direct Digital Synthesizer Module. Each module
uses a shared system clock and can be used either as two-channel phase coherent
LO, or as two independently controllable LOs. The primary programming API is an
IVI-NET driver, but there is a SCPI interface for hosting via a standalone SCPI server.
This document is intended to describe the SCPI command tree components and
provide details on how the commands map to the IVI interface.
DDS Subsystem
The M9347A has two direct digital synthesizer channels. Each channel is
independently controllable.
Frequency ([:DDS[1]|2])
[:DDS[1]|2]:FREQuency <val>[<unit>]
[:DDS[1]|2]:FREQuency? [MAXimum|MINimum]
This command sets the RF output frequency of the synthesizer.
The query returns the maximum or minimum allowable frequency if the optional
MAXimum or MINimum are used.
Example
:FREQ 6GHZ
The preceding example sets the frequency for synthesizer channel 1 to 6 GHz.
IVI Equivalent
KtM9347.Synthesizers[“1”].Frequency = 6e9;
Power Level ([:DDS[1]|2])
[:DDS[1]|2]:POWer <val>[<unit>]
[:DDS[1]|2]:POWer? [MAXimum|MINimum]
This command sets the RF output power of the synthesizer.
The query returns the maximum or minimum allowable power level if the optional
MAXimum or MINimum are used.
Example
:POW -5DBM
The preceding example sets the output power for synthesizer channel 1 to -5.0 dBm.
