Commands Listed in Alphabetical Order
Arguments
AUTO sets the va
lues. The probe range is automatically calculated.
MANual allows you to select various valid values for the probe connected to a
particular ch
annel.
Examples
CH2:PROBECONTROL AUTO sets the values and the probe range is automatically
calculated.
CH2:PROBECONTROL? might return :CH2:PROBECONTROL MANUAL indicating
that you can select various valid values for the probe connected to a particular
channel.
CH<x>:PROBEFunc:EXTAtten
This command is used to specify the input-output ratio, of external attenuation or
gain, between the signal and the instrument input channels.
The channel is specified by x. The value of x can range from 1 through 4.
The query form of this comma nd returns the user-specified attenuation. Note
that this command deals with an attenuation factor, not a gain factor, unlike
CH<x>:PRObe? (This command returns a value independent of the external
attenuation). For example, if you specify a 20x attenuation factor for channel 1,
the commands return the following values (assuming that a 1 x probe is presently
attached, since the external attenuation is used in combination with the probe
attenuation):
CH1:PRObe:EXTA? 20.00E+0
CH1:PRObe? 1.0E+0
This command is equivalent to selecting Attenuation from the Vertical menu, and
then either viewing or setting Ext Atten.
