41User Manual 1178.3834.02 ─ 05
The IEC 625 interface is in compliance with IEEE488 and SCPI. A computer for remote
control can be connected via this interface. To set up the connection, we recommend
that you use a shielded cable.
Note: To avoid electromagnetic interference (EMI) caused by open lines, always termi-
nate any connected IEC-bus cable with an instrument or a controller.
See also Chapter B.1, "GPIB-Bus Interface", on page 737 and Chapter 12, "Network
Operation and Remote Control", on page 346.
USB/USB In
●
Female USB type A connector, to connect devices like a keyboard, a mouse, a
memory stick, or the R&S NRP-Z3/Z4 cable for the R&S NRP power sensors
●
Female USB In connector (USB type B), for example for remote control.
Option: R&S SMAB-B86
See also Chapter 2.1.2, "Connecting USB Devices", on page 27.
LAN
The LAN interface can be used to connect the R&S SMA100B to a local network for
remote control, remote operation, and data transfer.
For details, see Chapter 2.1.3, "Setting Up a Network (LAN) Connection", on page 28.
V/GHz X-Axis
Output of a voltage ramp:
●
"V / GHz": the voltage is proportional to the frequency.
●
"X-Axis": output of a voltage ramp for the X deflection of an oscilloscope or an XY
recorder.
Z-Axis
Output of a voltage pulse, e.g. for the combined blanking and marker generation of net-
work analyzers.
Stop
Input and output for stopping the sweep in all modes.
This connector is bidirectional. Used as:
●
"Input": enables you to stop a sweep triggered by an external network analyzer.
●
"Output": enables the R&S SMA100B to stop the sweep of an external network
analyzer.
Marker User1
Output signal for marker or trigger signal.
Signal Valid
Output signal that marks the valid signal times (valid level and frequency) for all analog
modulations.
Alternatively, you can use this connector to synchronize pulse signals by activating the
"Pulse Sync" in the dialog Chapter 4.4.3, "Pulse Generator", on page 84.
Inst Trig
Input for external trigger of sweeps and list mode.
