Index Label Description
15 DC INPUT Option R&S ZNBT-B81"DC Inputs" provides four BNC inputs for DC measurements
(adjustable to different voltage ranges).
See Chapter 5.9.11, "DC Tab" , on page 466.
16 Device
Control This slot can be equipped with option R&S ZNBT-B12, providing a PCIe and a Direct
Control connector.
See Chapter 4.7.10, "Device Control" , on page 213.
17 GPIB Option R&S ZNBT-B10 provides a GPIB bus connector according to standard IEEE
488 / IEC 625.
See Chapter 10.2.3, "GPIB Interface" , on page 1254.
Input levels, EMC
The maximum input levels and voltages of the input connectors at the front and rear
panel must not be exceeded.
Use double shielded cables at the BNC rear panel connectors (EXT. TRIGGER OUT,
EXT TRIGGER IN, REF OUT, REF IN) and match signals with 50 Ω in order to comply
with EMC directives! See also
Chapter 3.1.5, "EMI Suppression" , on page 17.
3.3 Operating the Instrument
The following sections describe how to solve basic tasks that you will frequently
encounter when working with the instrument. In particular you can learn how to access
instrument functions and control dialogs without a mouse and/or keyboard.
Manual and remote control of the instrument
In contrast to the R&S ZNB, the R&S ZNBT is primarily intended to be remote-control-
led via the GPIB or LAN interface (see chapter 'Remote Control' in the user manual).
However, all instruments can be controlled manually, either using touchscreen and
frontpanel keys (R&S
ZNB only), an external monitor in combination with a mouse (see
also Chapter 3.1.9, "Connecting External Accessories" , on page 19) or via Remote
Desktop (see also Chapter 3.1.12, "Remote Operation in a LAN" , on page 24).
Manual and remote control of the R&S ZNB/ZNBT are described in separate chapters
of the user manual. Background information is provided in the reference chapter for
manual control, together with the dialogs that may be displayed on an external monitor.
To avoid redundancy, the reference chapter for remote control focusses on program
syntax and parameter ranges but contains only a short description of the command
functions.
Manual operation is particularly useful for getting to know the instrument and for trou-
ble shooting. The following sections describe how to access the instrument functions
and control dialogs at the graphical user interface.
