The INPut subsystem has the function of specifying some of the
characteristics of the 2461 TYPE C, such as attenuation,
coupling, impedance, etc. The query form of these commands
returns the setting previously specified.
INPut command summary
Selects x1 or X10 attenuation.
Selects AC or DC coupling.
Selects 50Ωor 1MΩ input impedance.
Separates or commons input channels 1 and 2.
Enables or disables the low-pass filter.
Selects relative trigger voltage level.
Selects absolute trigger voltage level.
Enables or disables hysteresis.
Selects comparator slope.
Enables, continuously or singly, or disables auto trigger.
Selects the minimum frequency the auto trigger algorithm
will detect reliably.
INPut[1 | 2]:ATTenuation <value | MINimum | MAXimum |
DEFault>
DESCRIPTION:
Selects the input block signal attenuator for the specified
channel. If the numerical <value> is less than or equal to 2,
the attenuator is set to 1. If <value> is greater than 2, the
attenuator is set to 10.
If this command is received while the functions
VOLTage:MIDDle, VOLTage:MAXimum,
VOLTage:MINinimum, RISE:TIME, FALL:TIME, PWIDTH
and NWIDTH are active, then the error –240 is generated
