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 mea-
surement results of the first four calculate blocks (
​
chapter 6.5, "CALCulate (Configuration
of Calculate Blocks)" , on page 221) 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 143.
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.
