Command Syntax Description
Set Amplifier
Mode to Digital
AMP:MODE: 0 Sets the operation of the digital amplifier to digital mode.
This includes setting the crossing point to that currently
specified for digital mode operation (AMP:CROSS:DIG)
and applying the current value of swing (AMP:SWING).
The default value of swing is the amplifier’s value for V
at
1 GHz, which is determined at the factory and place in
instrument memory. This command is not available for
instruments with linear (analog) amplifier types.
Get Amplifier
Mode
AMP:MODE? Returns 0 if the amplifier mode is set to analog and 1 if the
amplifier mode is set to digital. This command is not
available for instruments with linear (analog) amplifier
types.
Set Amplifier
Power On
AMP:POWer: 1 Sets amplifier power to “on” and returns 1 on receipt of
command.
Set Amplifier
Power Off
AMP:POWer: 0 Sets amplifier power to “off” and returns 1 on receipt of
command.
Get Amplifier
Power Status
AMP:POWer?
Returns 0 if the amplifier power is set to “off” and 1 if the
amplifier power is set to “on.” This command returns the
most recent requested power state, which may differ from
the amplifier’s currently active power state. AMP:SET? can
be used to verif
y
the last requested power state is active.
Get Amplifier
Status
AMP:SETpoint?
A 1 is returned and a steady green dot shows in the AMP
field of the instrument’s touchscreen when the amplifier is
fully ready and has reached the requested settings.
Otherwise, a 0 is returned and the green dot blinks.
Amplifier settings are updated quickly, typically within a
second. However, it is possible that an immediate query
after sending a command to adjust amplifier voltage will
find the amplifier in a transient state and return a zero.
Set the
Amplifier Swing
(Digital Mode)
AMP:SWING: N
N is a floating point value with a standard range of 3.0 to
7.0 V
pp
. This command sets the swing of the digital
amplifier when it operates in digital mode, and this value
can be set while operating in analog mode. Some factory-
customized units have an extended swing range. Use the
touchscreen GUI on the instrument to view the available
range. This command is not available for instruments with
linear
(
analo
g)
amplifier t
y
pes.
Get the
Amplifier Swing
(Digital Mode)
AMP:SWING?
Returns a floating point value with units of Vpp. This is the
swing setting applied when the digital amplifier operates in
digital mode. This value can be retrieved while operating in
analog mode. This command is not available for
instruments with linear
(
analo
g)
amplifier t
y
pes.
Set the
Amplifier Swing
to V
(Digital Mode)
AMP:SWING:VPI
Sets the swing to the amplifier’s V
at 1 GHz and returns 1
on receipt of command. This V
value is found for each
instrument at the factory and saved to memory. It is the
“optimal swing” setting applied when the V
button on the
touchscreen interface is pressed. This command is not
available for instruments with linear (analog) amplifier
t
y
pes.
