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>"
