Operating Manual 1145.1084.12 – 30 903
<Ch>
Channel number.
POSitive
The LO frequency is always above the measured RF frequency.
NEGative
The LO frequency is always below the measured RF frequency.
AUTO
The analyzer auto-selects the local oscillator frequency, depending on the
receiver (RF) frequency and the test port.
*RST value
AUTO
SCPI,
Command
Types
Device-specific, command or query.
Example:
*RST; :SWE:TYPE?; :FREQ:SBAN?
Query the *RST values for the sweep type and the sideband setting. The
response is LIN (linear frequency sweep) and AUTO (automatic setting of the LO
frequency).
[SENSe<Ch>:]FREQuency:SPAN <span>
Defines the width of the measurement and display range for a frequency sweep.
<Ch>
Channel number.
<span>
Frequency span 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 range of the analyzer: f
MAX
- f
MIN
SCPI, Command
Types
Confirmed, command or query.
Example:
See [SENSe<Ch>:]FREQuency:CENTer
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
Minimum frequency of the analyzer: MIN
SCPI, Command
Types
Confirmed, command or query.
Example:
See [SENSe<Ch>:]FREQuency:STOP
Note: If the start frequency entered is greater than the current stop frequency
