Keysight 53220A/53230A User’s Guide 45
How the User’s Guide is Organized
This user’s guide is written for the operator using the instrument from the front
panel, and for the programmer controlling the counter from a remote (LAN, USB,
GPIB) interface. As such, most topics include a front panel key sequence followed
by the corresponding SCPI commands. For example:
--------------------------------------------------------------------------------
The input impedance of the 53220A/53230A counter can be set to either 50 Ω or
1 MΩ using the command:
INPut[{1|2}]:IMPedance {<impedance>|MINimum|MAXimum| DEFault}
INPut[{1|2}]:IMPedance? [{MINimum|MAXimum|DEFault}]
(query form)
--------------------------------------------------------------------------------
The description of operation which follows typically applies to both front panel
and remote usage.
