7.4 Diagnostics
The diagnostics mode can be entered from the RS-232 port as well as from the front panel. The
diagnostics commands available are listed below.
NOTE
The diagnostics mode may only be entered via the RS-232 port when
the calibrator is in stand by mode.
Table 7-5: Diagnostic Commands
Command Function
"D ENTER<CRLF>" Enter diagnostics mode
"D EXIT<CRLF>" Exit diagnostics mode
"D PREV<CRLF>" Go to previous test
"D NEXT<CRLF>" Go to next test
"D ON<CRLF>" Turn test signal ON
"D OFF<CRLF>" Turn test signal OFF
"D PAUSE<CRLF>" Pause analog output test
"D RESUME<CRLF>" Resume analog output test
These commands may be used whether the diagnostics have been entered from the keyboard
(SETUP-DIAG) or the RS-232 ("D ENTER <CRLF>"). However, when the diagnostics are
entered via the keyboard, no feedback is sent to the RS-232 channel. This prevents the RS-232
output from getting unnecessarily cluttered with diagnostic data.
In addition to the above commands, three special diagnostics commands have been added to
provide complete control over a remote Analyzer. These commands may be executed no matter
what mode the instrument is in.
