Remote Control Fundamentals
NRP2
170User Manual 1173.9140.02 ─ 07
line, the keyboard including ESC/LOCAL has been disabled via the LLO command. In
this case, returning to local mode is only possible with the remote control command
GTL or by a power-on reset.
5.1.2 Measurement Modes
To simplify operation in the manual mode, preset values are used in some cases for
the trigger system (TRIGger
command) and the timing of the measurement
(SENSe[1..4]:TIMing:EXCLude:STARt and :STOP) when a measurement mode
such as "ContAv", "Burst", "Timeslot" or "Trace" is selected, see table 5-3, Automatic
settings for manual selection of a measurement mode. This is not the case in the
remote control mode. Here the trigger system and the timing can be configured by the
user as required.
5.1.3 Calculate Blocks
The R&S NRP2 manages 8 internal calculate blocks. Each calculate block has two
input channels (primary and secondary channel) to which one of up to 4 power sensors
can be assigned. The channels can be processed together by means of a selectable
function. The result is available at the output of the calculate block. In the manual
mode, the measurement results of the first four calculate blocks (chapter 6.5, "CALCu-
late (Configuration of Calculate Blocks)", on page 224) are shown in windows 1 to 4,
while 8 calculate blocks are available in the remote control mode.
5.2 Connecting a Controller to the Base Unit
5.2.1 Settings in Base Unit
Before a link can be established between the controller and the R&S NRP2, the
R&S NRP2 must be assigned a corresponding address.
In the manual control mode, the address is set in the "System" > "Remote" dialog box,
see chapter 4.7.1, "Configuring the remote control interfaces", on page 145.
In remote control mode, the SYSTem:COMMunication:.. commands serve this pur-
pose.
GPIB configuration (IEC/IEEE bus):
1.
Select "GPIB" as the active interface.
2. Enter the GPIB address. Any value between 0 and 30 is permissible.
USB configuration:
► Select "USB" as the active interface.
