External Generator Control – Option R&S FSP-B10
4.346 Operating Manual 1302.6163.12 - 03
•IFC
This field selects the interface type of external generator 1 or 2. The following
types are available:
– GPIB: GPIB only, suitable for all generators of other manufacturers and some
Rohde & Schwarz instruments
– TTL: GPIB and TTL interface for synchronization, for most of the Rohde &
Schwarz generators, see table above.
The two operating modes differ in the speed of the control: Whereas, with pure
GPIB operation, each frequency to be set must be individually transferred to the
generator, additional use of the TTL interface permits to program a total frequency
list at once and subsequently perform the frequency stepping via TTL handshake,
which is a big advantage in terms of speed.
• GPIB ADDR
GPIB address of the respective generator. Addresses from 0 to 30 are possible.
•MODE
Operating mode of generator. The generator activated using the FREQUENCY
SWEEP softkey is automatically set to remote mode (REMOTE), the other to
manual operation (LOCAL).
• FMIN FMAX
Frequency range of generator. Select the start and stop frequency of the
R&S ESU in a way that the specified range is not exceeded. If the start frequency
lies below F MIN, the generator is only switched on when F MIN is reached. If the
stop frequency lies above F MAX, it is limited to F MAX when the generator is
switched on using the EXT SRC ON/OFF softkey.
• PMIN PMAX
Level range of generator. This field defines the allowed input range for the
POWER column in the FREQUENCY SWEEP table.
Remote command: SYST:COMM:RDEV:GEN2:TYPE 'SMA01A'
SYST:COMM:RDEV:GEN:LINK TTL
SYST:COMM:GPIB:RDEV:GEN1:ADDR 28
Generators equipped with the TTL interface can also be operated with GPIB only.
Only one of the two generators can be operated with TTL interface at a time. The
other generator must be configured for GPIB.
