Keysight 53100 series counter emulation mode
The 53220A/53230A’s emulation mode enables the Keysight 53132A SCPI 
command set to be used with the counter.
The emulation mode can also be enabled using the command:
SYSTem:LANGuage "<language>"
SYSTem:LANGuage? (query form)
- language selects the SCPI command set used. Specifying 53132A enables the 
emulation mode. Specifying either 53220A or 53230A disables the mode.
With 53100-series compatibility mode selected, all programming is through the 
counter's remote interface (LAN, USB, GPIB). The counter display responds 
according to the remote commands received.
Pressing any front panel key while in 53100 compatibility mode returns the 
counter to 53200 series mode as prompted. Setting or changing to either mode 
requires the instrument to be restarted. When updating the instrument firmware 
“53220A or 53230A mode” must be set.
Documentation of the 53132A command set is not provided with the (53220A/
53230A) instrument. Use of the older SCPI command set is discouraged for new 
use, but is available for customers who require it.
