Reference

IVI Equivalent

KtM9347.Synthesizers[“1”].PowerLevel = -5.0;

Phase Offset ([:DDS[1]|2])

[:DDS[1]|2]:PHASe <val>
[:DDS[1]|2]:PHASe? [MAXimum|MINimum]

This command applies a phase rotation, in degrees, to the data generated by the
synthesizer.

The query returns the maximum or minimum allowable phase rotation if the optional
MAXimum or MINimum are used.

Example

:DDS2:PHAS -45

The preceding example applies a -45° phase rotation to synthesizer channel #2.

IVI Equivalent

KtM9347.Synthesizers[“2”].PhaseOffset = -45.0;

Output Enabled ([:DDS[1]|2])

[:DDS[1]|2]:OUTPut[:STATe] ON|OFF|1|0
[:DDS[1]|2]: OUTPut[:STATe]?

This command enables or disables the RF output of the synthesizer.

Example

:DDS2:OUTP OFF

The preceding example disables the RF output of synthesizer channel #2.

IVI Equivalent

KtM9347.Synthesizers[“2”].OutputEnabled = false;

Calibration Subsystem (:CALibration)

System Clock Calibration

:CALibration:SCLK

This command invokes an internal alignment to lock the DDS chips to the system
clock.  This alignment must be performed whenever the system clock source is
changed.

Example

:CAL:SCLK

IVI Equivalent

KtM9347.Calibration.Align( AlignmentType.SystemClock );
