LO/IF ports for external mixers - Option R&S FSP-B21
Data and type designation of the mixer can be entered into the header of the
table.The columns contain the frequencies and the corresponding conversion
losses.
Name - File name
The name of the table is identical with the name of the file (without extension) in
which the table is stored. The entry in this field is mandatory. The name may consist
of a maximum of 10 characters and ends with the harmonic used, e.g. Mixer_2. The
.ACL extension will automatically be appended at storing.
Remote command:
CORR:CVL:SEL 'LOSS_T_4'
Mixer - Type designation of mixer
The information in the Mixer field shows the user at a glance to which mixer a file

Bias - Bias setting
The bias current required for the mixer has to be entered in this field. The setting
range is between -10 mA and +10 mA.
The entry in this field is mandatory.
The current corresponds to the short-circuit current. The actual bias current is
lower because of the forward voltage of the mixer diode(s).
