2.2.1 Description of the Connectors
LF
(path A only)
Output for internal LF modulation generator signal.
See also data sheet and chapter 5.5.12.1, "LF Generator Overview", on page 246,
chapter 5.5.12.2, "LF Output", on page 246.
MARKER 1B
Output for user-programmable marker signal 1 of path B for triggering and control of
external devices. Marker outputs are permanently assigned (see "MARKER 1, 2"
on page 26).
MARKER 1/ MARKER 2
Rear Panel Connectors for path A (option R&S SMU-B81) and path B (option R&S SMU-
B82).
These options are recommended for use of the instrument in a 19" rack. Installing the
instrument in a 19" rack requires a rack adapter or an adapter for telescopic sliders (refer
to data sheet for order number).
Marker outputs are permanently assigned (see "MARKER 1, 2" on page 26).
See also chapter 2.3.2, "Placing or Mounting the Instrument", on page 33.
AC SUPPLY AND POWER SWITCH
When the R&S SMU is connected to the AC supply, it automatically sets itself to the
correct range for the applied voltage (range: see type label). There is no need to set the
voltage manually or change fuses.
The instrument comes with or without a power switch, depending on the design of the
otherwise technically equivalent power supply unit.
The power switch can be set to two positions:
●
0
The instrument is disconnected from the mains.
●
I
The instrument is power-supplied. It is either ready for operation (STANDBY) or in
operating mode, depending on the position of the ON/STANDBY switch on the instru-
ment front.
See also data sheet and chapter 2.3.3, "Connecting the Instrument to the AC Supply",
on page 34.
I OUT / Q OUT
(path A or path B)
Direct output or Differential (non-inverting) output for analog I/Q signal.
Option option R&S SMU-B16 is required.
See also chapter 5.7.3, "Output of the Baseband Signal - I/Q Out", on page 308.
