INPut

The INPut command subsystem controls characteristics of the input signal, including ON/OFF state and low-pass filtering. The command defaults to channel 1 if you do not specify a channel in the command syntax (e.g., INP ON is same as INP1 ON).

Subsystem Syntax

INPut[<channel>]

 

 

:FILTer[:LPASs]:FREQ

1.5E3 6E3 25E3 100E3

 

(valid for E1564A only)

 

 

:FILTer[:LPASs]:FREQ?

 

 

:FILTer[:LPASs][:STATe]

ON 1 OFF 0

 

:FILTer[:LPASs][:STATe]?

 

[:STATe] ON 1 OFF 0

 

[:STATe]?

 

INPut:FILTer[:LPASs]:FREQ

 

 

INPut[<channel>]:FILTer[:LPASs]:FREQ 1.5E3 6E3 25E3 100E3 sets the

 

filter frequency for the 4-channel E1564A Digitizer. The filters are 2-pole

 

Bessel filters and <channel> is 1 through 4.

NOTE

 

The 2-channel E1563A Digitizer has a fixed 25 kHz filter. The E1563A will

 

accept this command but cannot change the filter and will not generate an

 

error.

 

Comments

 

Filter is Set to Nearest Value: For the E1564A 4-channel digitizer, the filter

 

will be set to the nearest value that can be achieved by the value specified

 

in the command. For example, if you specify 10E3, the filter is set to 6K or

 

if you specify 20E3, the filter is set to 25K. For the E1563A 2-channel

digitizer, the filter will be 25 kHz regardless of what value you input (see above note).

Executable when initiated: NO

Coupled Command: NO

Reset (*RST) Condition: Filter state OFF

INPut:FILTer[:LPASs]:FREQ?

INPut[<channel>]:FILTer[:LPASs]:FREQ? queries the present filter frequency setting on the specified channel.
