Agilent Technologies 8163A - Signal Conditioning; The Input and Output Commands

Measurement Operations & Settings Signal Conditioning
148 Agilent 8163A/B, 8164A/B & 8166A/B Mainframes, Fifth Edition
Signal Conditioning
The commands in this section allow you to control Agilent 8156x, and
8157x 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 (α) for the instrument. The attenuation factor is used, together
with an offset factor (α
Offset
) to set the filter attenuation ( α
filter
).
α
(new)
(dB) = α
filter (new)
(dB) + α
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
α
filter
= 0dB
The value where
α
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 (α), in dB.
α (dB) = α
filter
(dB) + α
Offset
(dB)
parameters: MIN | DEF | MAX Returns the minimum, default, or maximum value of the attenuation fac-
tor possible.
response: 4 byte Intel floating point; attenuation in dB.
example: INP1:ATT? → 14<END>
affects: All attenuator modules
