R&S FSQ Signal Analyzer - Rohde & Schwarz

R&S FSQ Instrument Functions
EXTERNAL
MIXER
EXT MIXER ON/
OFF
LO/IF ports for external mixers - Option R&S FSU-B21
The EXTERNAL MIXER softkey opens a submenu for setting the parameters of the
external mixer. The softkey automatically switches on the external mixer.
External mixing is switched on or off by the EXT MIXER ON/OFF softkey.
Remote command: MIX ON
SELECT BAND The SELECT BAND softkey opens a submenu for selecting the waveguide band
and the harmonic to be used and for setting all necessary parameters. The configuration
can be stored using the function SAVE of FILE menu.
Remote command: --
When the table SELECT BAND is open and you press Enter in a BIAS field the table
is automatically closed. When the BIAS value is now changed the immediately effect
on the measurement trace can be seen.
The table contains the following parameters for each band:
BAND - Designation of waveguide band
Remote command: MIX:HARM:BAND E
RANGE - Frequency range
The frequency range of the waveguide band or the frequency range which is covered
by the selected harmonic is shown in this field.
Remote command: --
HARMONIC# - Order of harmonic
Order of harmonic used for conversion The order is selected automatically depending
on the definition made in the EVEN / ODD HARMONICS column. The lowest
order is selected that allows conversion of input signals in the whole band.
If due to LO frequency the conversion is not possible using one harmonic, the band
is splitted. Frequency range and order of harmonic of the resulting parts are shown
within the field.
