717 Operating Manual 1403.7458.32 ─ 14
Example: FREQ:MODE SWE
sets the SWEep mode.
Manual operation: See "State - Frequency Sweep" on page 262
[:SOURce<hw>]:FREQuency:MULTiplier <Multiplier>
Sets the value for the multiplication factor of a subsequent downstream instrument.
Parameters:
<Multiplier> float
Range:
1 to dynamic
Increment: 0.001
*RST:
1
Example:
FREQ:MULT 1
sets the multiplication factor to 1.
Manual operation: See "Multiplier" on page 203
[:SOURce<hw>]:FREQuency:OFFSet <Offset>
Sets the frequency offset of a downstream instrument, for example a mixer.
If you have specified an
OFFSet
and / or a
MULTiplier
factor, the actual frequency
at the RF output does not change, but rather the value queried with [:SOUR]:FREQ? ,
according to the following formula:
f
FREQ
= f
RFout
* f
MULTiplier
+ f
OFFSet
Parameters:
<Offset> float
Increment: 0.01
*RST:
0
Example: FREQ:OFFS 500kHz
sets the frequency offset to 500 kHz.
Manual operation: See "Offset" on page 203
[:SOURce<hw>]:FREQuency:PHASe:CONTinuous:STATe <State>
Activates/deactivates phase continuous frequency settings. For a given RF frequency
setting, phase continuous frequency changes are possible in a limited frequency range
(see
Chapter 5.5.3.2, "Phase Continuous Frequency" , on page 205).
The output sinewave is phase continuous, i.e there will be no phase discontinuity or
glitch when changing the frequency.
Note: Restricted structure of command line. As long as phase continuous mode is
active, only one command in a command line is processed. A second command in the
command line will be ignored.
