30
CT command
Syntax:
CTx [yyy]
Parameters:
x represents a digit that has only 2 valid values: “I” or “S”.
yyy is a decimal digit value between 40 and 140, valid if x =S.
Description:
The command sets/interrogates the level on
TTL/CMOS
output. The command is
available only on
EXTERNAL VCG
and
INTERNAL SWEEP
mode.
If x = S the CMOS output level will take values between 4.0 and 14.0 V.
If x = I the CMOS level value will be sent to terminal
Example:
CTS123 – sets the
TTL/CMOS
output level at 12.3V
Message returned to terminal:
“TTL/CMOS output: 12.3 V”
if the command is sent correctly.
“Wrong value sent”
if “yyy” parameter sent was not a valid value.
CD command
Syntax:
CDx[yyy]
Parameters:
x represents a digit that has only 2 valid values: “I” or “S”.
yyy is a decimal digit value between 0 and 100, valid if x = S.
Description:
The command sets/interrogates the duty cycle of the signal output on
OUTPUT
jack. The command is available only on
EXTERNAL VCG
and
INTERNAL
SWEEP
mode.
If x = S, the duty cycle will take values between 0 and 100%.
If x = I, the duty cycle value will be sent to the terminal.
Example:
CDS0 – sets the duty cycle to 0%.
Message returned to terminal:
“Duty cycle: yyy %”
if the command is sent correctly.
“Wrong value sent”
if the “yyy” parameter sent was not a valid value.
CW command
Syntax:
CWx[yyy]
Parameters:
x represents a digit that has only 2 valid values: “I” or “S”.
yyy is a decimal digit value between 1 and 100, valid if x = S.
Description:
The command sets/interrogates the ratio factor used to calculate the
STOP
frequency
of the output signal at
OUTPUT
jack. The command is available only on
INTERNAL SWEEP
mode.
If x = S the value of the ratio will take values between 1 and 100.
If x = I the ratio factor used to calculate the
STOP
frequency will be sent to
terminal.
Example:
CWS45 – sets the ratio applied to the START frequency at the value of 45.
Message returned to terminal:
“Sweep width ratio: yyy %”
if the command is sent correctly.
“Wrong value sent”
if the “yyy” parameter sent was not a valid value.
“Command not allowed in current mode”
if INTERNAL SWEEP mode isn’t the
current working mode.
CS command
Syntax:
CSx [yyyy]
Parameters:
x represents a digit that has only 2 valid values: “I” or “S”.
