Note that all numeric variables can be expressed in integer, floating point or exponential formats (i.e., the number
five can be 5, 5.0, or .5E1). Strings are sent as a sequence of ASCII characters.
4.2.1 Reference and Phase Commands
PHAS(?){x}
The PHAS command sets or queries the reference phase shift. The parameter x refers to the
phase (real number, unit: °). The PHAS x command will set the current phase shift to x°.
The value of x is rounded to 0.01°. The phase can be programmed from -180° to +180°. For
example, send command “PHAS -179.0” and the phase shift will be set to -179°. The
PHAS? command queries the phase shift.
FMOD(?){i}
The FMOS command sets or queries the reference source. The parameter i selects external
reference (i=0), internal reference (i=1) or internal sweep reference (i=2).
FREQ(?){f}
The FREQ command sets or queries the reference signal. The FREQ?
command will return the current reference frequency (internal or external).
RSLP(?){i}
The RSLP command sets or queries the trigger way of reference signal when in external
reference mode.
The parameter i selects <TTL> rising edge (i=0) or <Sine> zero crossing (i=1). When the
frequency is less than 1 Hz, the <TTL> reference must be used.
SWPT(?){i}
The SWPT command sets or queries the mode of internal frequency sweep. The parameter i
selects <Linear> (i=0) or <Log> (i=1).
SLLM(?){f}
The SLLM command sets or queries the <Start> frequency in internal frequency sweep
mode. The SLLM? command will return the start frequency. The range of f is 0-100kHz
and the minimum resolution is 1mHz.
SULM(?){f}
The SULM command sets or queries the <Stop> cutoff frequency in internal frequency
sweep mode. The SULM? command will return the cutoff frequency. The range of f is
0-102kHz and the minimum resolution is 1mHz.
SSLL(?){f}
The SSLL command sets or queries the step frequency in <Linear> internal frequency
sweep mode. The SSLL? command will return the step frequency. The range of f is
0-102kHz and the minimum resolution is 1mHz.
SSLG(?){x}
The SSLG command sets or queries the percentage in <Log> internal sweep mode. The
SSLG? command will return the percentage in <Log> frequency sweep mode. The range of
x is 0-100 and the minimum resolution is 0.001. x=50 means that the percentage is 50%.
STLM(?){i}
The STLM command sets or queries the step time in internal frequency sweep mode. The
STLM? command will return the step time of internal sweep mode. The range of i is
1ms-100,000ms and the minimum resolution is 1ms.
SWRM(?){i}
The SWRM command sets or queries the running mode in internal frequency sweep
mode. The parameter i selects <STOP> (i=0) , <Single> (i=1) or <Loop> i=2).
