Load an arbitrary waveform from the USB drive and set up the balance gain (channel 2 down by 1.02%) and balance
offsets (120 mV for channel 1 and -38 mV for channel 2):
FUNC:ARB "USB:\qam32.barb"
FUNC:ARB:BAL:GAIN 1.02
FUNC:ARB:BAL:OFFS1 0.12
FUNC:ARB:BAL:OFFS2 -0.038
FUNC:ARB:BAL ON
This feature can be used to compensate for minor variations in the load impedances on the two channels, or for
l
minor differences between the two channels of information in the original dual arbitrary waveform file.
When the <state> is on, both channels must stay on the same amplifier range.
l
This setting is stored as part of the instrument state, and it is affected by *RST.
l
FUNCtion:ARBitrary:BALance:GAIN {< percent >|MAXimum|MINimum}
FUNCtion:ARBitrary:BALance:GAIN? {MAXimum|MINimum}
This command requires the IQ Player option.
Sets the gain balance ratio for dual arbitrary waveforms.

Load an arbitrary waveform from the USB drive and set up the balance gain (channel 2 down by 1.02%) and balance
offsets (120 mV for channel 1 and -38 mV for channel 2):

FUNC:ARB:BAL ON
Both channels must stay on the same amplifier range.
l
A value of 0 means that both channels use their current amplitude. A positive value means that the amplitude of
l
channel 2 is pushed down, while the amplitude of channel 1 remains constant, a negative value pushes channel 1
down while holding channel 2 constant. See the following table for examples.
