Instrument-Control Commands
Operating Manual 1303.6580.32-05
513
Activate a frequency sweep and select the ratio B1/A2 as measured parameter
for channel and trace no. 1.
FREQ:CENT 100MHz
Set center frequency to 100 MHz.
FREQ:SPAN 50000
Set frequency span to 50 kHz, leaving the center frequency unchanged.
Note:
The measurement range defined by means of the span and the current center frequency
([SENSe<Ch>:]FREQuency:CENTer), must not exceed the allowed frequency range of the
analyzer. If necessary, the center frequency is adjusted to f
MIN
+ Span/2 or f
MAX
– Span/2.
[SENSe<Ch>:]FREQuency:STARt <start_frequency>
Defines the start frequency for a frequency sweep which is equal to the left edge of a Cartesian diagram.
<Ch>
Channel number.
<start_frequency>
Start frequency of the sweep.
Range [def. unit]
Depending on the instrument model [Hz]. The increment (parameters UP or
DOWN) is 0.1 kHz.
*RST value
9 kHz (larger than the minimum frequency of the analyzer).
SCPI, Command
Types
Confirmed, command or query.
Example:
FUNC "XFR:POW:RAT B1, A2"
Activate a frequency sweep and select the ratio B1/A2 as measured
parameter for channel and trace no. 1.
FREQ:STAR 100000
Set start frequency to 100 kHz.
FREQ:STOP 10MHz
Set stop frequency to 10 MHz.
Note:
If the start frequency entered is greater than the current stop frequency
([SENSe<Ch>:]FREQuency:STOP), the stop frequency is set to the start frequency plus the
minimum frequency span ([SENSe<Ch>:]FREQuency:SPAN).
[SENSe<Ch>:]FREQuency:STOP <stop_frequency>
Defines the stop frequency for a frequency sweep which is equal to the right edge of a Cartesian diagram.
<Ch>
Channel number.
<stop_frequency>
Stop frequency of the sweep.
Range [def. unit]
Depending on the instrument model [Hz]. The increment (parameters UP or
DOWN) is 0.1 kHz.
*RST value
Maximum frequency of the analyzer: MAX
