T
he short and simple operating sequence below shows how to put the instrument into operation and
quickly set its basic functions. The remote control address, which is factory–set to 10.0.0.10, subnet
mask 255.255.255.0 for LAN operation and 20 for operation via GPIB, is used. If you want to change the
IP address, see "Setting the Remote Control (IP/GPIB) Address".
To prepare for remote control
1. Connect the instrument to the LAN or directly to the GPIB controller (option GPIB Interface,
R&S FSL–B10).
For details refer to the Quick Start Guide, appendix B.
2. Switch on the instruments.
3. Write and start the following program on the controller:
status = viOpenDefaultRM(defaultRM)
' Open default resource manager
Cmd = "*RST;*CLS"
status = viWrite(vi, Cmd, Len(Cmd),
retCount)
' Reset instrument and clear status
registers
Cmd = "FREQ:CENT 100MHz"
status = viWrite(vi, Cmd, Len(Cmd),
retCount)
' Set center frequency to 100 MHz
Cmd = "FREQ:SPAN 10MHz"
status = viWrite(vi, Cmd, Len(Cmd),
retCount)
' Set span to 10 MHz
Cmd = "DISP:TRAC:Y:RLEV –10dBm"
status = viWrite(vi, Cmd, Len(Cmd),
retCount)
' Set reference level to –10 dBm
The instrument now performs a sweep in the frequency range of 95 MHz to 105 MHz.
Setting the Remote Control (IP/GPIB) Address
In order to operate the instrument via remote control, it must be addressed using the set IP or GPIB
address. The remote control address is factory–set (for details refer to "Getting Started"), but it can be
changed, if it does not fit in the network environment.
To change the GPIB address via R&S FSL
For details see Quick Start Guide, chapter 2 "Preparing for Use".
To change the GPIB address via GPIB
status = viOpenDefaultRM(defaultRM)
' Open default resource manager
status = viOpen(defaultRM, "GPIB:20::INSTR", 0,
5000, vi)
' Open connection to instrument
with old address
Cmd = "SYST:COMM:GPIB:ADDR 18"
status = viWrite(vi, Cmd, Len(Cmd), retCount)
' Set instrument to new address
status = viClose(vi)
status = viOpen(defaultRM, "GPIB:18::INSTR", 0,
5000, vi)
' Close old connection and reopen
with new address
