32 53220A/53230A User’s Guide
1 Preparation for Use
Securing the Instrument
The 53220A/53230A counter can be secured to the National Industrial
Security Program Operating Manual (NISPOM) standard as shown below.
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 M
Ω using the command:
INPut[{1|2}]:IMPedance {<impedance>|MINimum|MAXimum|
DEFault}
INPut[{1|2}]:IMPedance? [{MINimum|MAXimum|DEFault}]
(query form)
