Operating basics
Settings
Frequency
Pressing the Freq button allows you to adjust the carrier frequency of the front
panel BNC (LF Out) and Type N (RF Out) outputs. A frequency can be entered in
any of the following units: GHz, MHz, kHz, or Hz using the unit buttons on the
front panel. The frequency resolution is 1
μ Hz at all frequencies. The frequency
setting determines which outputs are active at any given time. Enabled outputs
are noted in the front panel display and in the RF button light on the front panel.
None of the outputs operate across the entire frequency range, but are dependant
on the instrument model.
Phase The Phase setting is accessed through the main menu: RF/LF > Phase . This
setting shows the relative phase of the output in degrees and is adjustable over
±360º. If the phase adjustment exceeds 360º, the phase is displayed modulo 360º.
The displayed phase is reset to 0° whenever the carrier frequency is changed. The
phase resolution depends on the current setting of the frequency. For frequencies
up to 100 MHz, the phase resolution is 0.01°, with reduced resolution for higher
frequencies.
Amplitude
Pressing the Ampt button allows you to adjust the output amplitude or power
of the displayed output. If an output is set below its minimum value, it will be
disabled. This is indicated on the display as
RFOFF and the RF LED button on
the front panel being extinguished. Amplitude can be displayed in units of dBm,
dBuV, or V
RMS
. All stated values assume a load termination of 50 Ω .
LF Offset
The Offset setting for the LF Out output is accessed through the main menu:
RF/LF
> LF Offset . This setting shows the output offset voltages. Only the LF
Out (BNC) output has a settable DC offset. The Type N RF output is AC coupled
and so has no DC offset setting. The DC offset for the LF Out is always accessible
and active (independent of the frequency setting).
I/Q Offset
The Offset setting for the I/Q outputs is accessed through the main menu:
AWGN/IMP > I Offset or Q Offset . This setting shows the offset as %.
RF On/Off
The front panel outputs can be turned on and off by pressing the RF button on
the front panel. When the RF is off, the RF LED button on the front panel is
extinguished and the RFON text on the display is grey. When RF is on, the RF
LED button on the front panel is lit and RFON on the display is yellow.
