Syntax
:
IN
Parameters
: None
Description
:
Sends to terminal the unit’s serial number.
Example
:
IN
Message returned to terminal
: “
Serial Number: XXX-YYYY-ZZZZ
” where XXX-YYYY-ZZZZ
Represents the serial number according to BK Precision codification.
Type III command: commands for setting mode and its parameters
.
CM command
Syntax:
CMx
Parameters:
x is a 3 possible value digit: 0, 1 or 2.
Description:
Sets the unit’s working mode according to the value of the “x” parameter. If x > 2
the unit remains in the working mode and a specific error message is sent to
terminal.
If the mode is already set, any action is aborted and a specific message is sent to
terminal.
Example:
CM0 – the “
EXTERNAL VCG
” mode is engaged.
Message returned to terminal:
“Mode EXTERNAL VCG engaged
” if x = 0
“Mode INTERNAL SWEEP engaged
” if x = 1
“Mode
FREQCOUNTER
engaged
” if x = 2
“Mode unavailable”
if x > 2
“Mode already set”
to enable a mode which is already running.
CF command
Syntax:
CFx [yyyyyyyyyy]
Parameters:
x represents a digit, valid for the following values: “I”, “U”, “D”, “S”.
yyyyyyyyyy is a decimal digit value who takes values between 0 and 1000000000,
valid only if x = S.
Description:
Case 1
In
EXTERNAL VCG
and
INTERNAL SWEEP
mode, this command
sets/modifies/interrogates the value of the start frequency.
If x = S, the start frequency will be set at the value of the “yyyyyyyyy” parameter
which takes values between 0.00Hz and 10000000.00Hz with a 0.01HZ resolution.
If x = U or x = D, the working domain of the “yyyyyyyyy” parameter will be
increased or respectively decreased.
If x = I the value of the start frequency will be sent to the terminal.
Case 2
In
FREQCOUNTER
mode this command modifies the gate period used in
measuring frequency or asks about the measured frequency.
If x = U or x = D the gate period will be increased or respectively decreased.
