Attenuator modules
The INPut and OUTput commands
command: :INPut[n][:CHANnel[m]]:ATTenuation
syntax: :INPut[n][:CHANnel[m]]:ATTenuation<wsp><value>[dB] | MIN | DEF | MAX
description: Sets the attenuation factor (a) for the instrument. The attenuation factor is used, together with an offset factor (a
Offset
) to
set the filter attenuation ( a
filter
).
a
(new)
(dB) = a
filter (new)
(dB) + a
Offset
(dB)
Set the attenuation factor by sending a value (the default units are dB), or by sending MIN, DEF, or MAX.
parameters: <value>[dB]
MIN | DEF
MAX
The attenuation in dB.
The values where a
filter
= 0dB
The value where a
filter
is at its greatest.
response: none
example: INP1:ATT 14dB
affects: All attenuator modules
command: :INPut[n][:CHANnel[m]]:ATTenuation?
syntax: :INPut[n][:CHANnel[m]]:ATTenuation?<wsp> MIN | DEF | MAX
description: Returns the current attenuation factor (a), in dB.
a (dB) = a
filter
(dB) + a
Offset
(dB)
parameters: MIN | DEF | MAX Returns the minimum, default, or maximum value of the attenuation factor possible.
response: 4 byte Intel floating point; attenuation in dB.
example: INP1:ATT?
-> 14<END>
affects: All attenuator modules
