Next Page
Next Page and Previous Page menu keys move you between pages of the log, if it fills more than one page.
These keys are grayed out in some cases:
•
If on the last page of the log, the Next Page key is grayed-out
•
If on the first page of the log, the Previous Page key is grayed-out.
•
If there is only one page, both keys are grayed out.

Verbose SCPI On/Off
When you turn Verbose SCPI on, additional information is returned when you send the :SYSTem:ERRor?
query. The additional information consists of the characters that stimulated the error. This can aid you in
debugging your test programs by indicating where in the parsing of a SCPI command the instrument
encountered an invalid command or query.
Specifically, with Verbose SCPI on, the SYSTem:ERRor? query is expanded to show the SCPI data
received, with the indicator <Err> at the point in the stream that the error occurred.
Verbose SCPI has no effect on the Show Errors screen or front panel Message Line; it only changes the
response to the :SYST:ERR? query.
See the example below, where the invalid command “SENS:BOGUS” is sent:
Normal response to :SYST:ERR (using the Telnet window):
SCPI> SENS:BOGUS
SCPI> SYST:ERR?
–113,"Undefined header"
Now after turning on Verbose SCPI:
SCPI> SYST:BOGUS
SCPI> SYST:ERR?
–113,"Undefined header;SYST:BOGUS<Err>"
154
