Spectrum analyser remote access
The main spectrum analyser in the testbed room is a Rohde & Schwarz FSVR real-time analyser.
- Host name: ctvr-analyser.cs.tcd.ie
- IP address: 134.226.55.156
- Frequency range: 10Hz - 7GHz
- Frequency range: 10Hz - 7GHz
- Support for IQ analysis (inc. OFDM)
- Maximum sampling rate for IQ acquisition: 128MS/sec
The spectrum analysers are situated as shown in the testbed layout diagram; however, we can easily relocate the receive antenna of the spectrum analyser around the lab if needs be for a certain experiment. We also have in the testbed:
- Rohde & Schwarz SMU 200A - Vector Signal Generator
- Anritsu MS2781B - Signal Analyser
- Anritsu MS2721B - Spectrum Master (handheld spectrum analyser)
Probably the easiest way to acquire data from the Rohde & Schwarz spectrum analyser is using the testbed Windows node "Trinity-8170896" which is accessible via VNC through the ctvr-gateway node. This node runs Rohde & Schwarz IQWizard, a programme which allows simple acquisition of IQ data, in a range of formats. However, remote access directly to the spectrum analyser via VNC is also available.
Remote access via VNC
The spectrum analyser can be accessed from any of the testbed nodes or from the ctvr-gateway server. Information on obtaining access to these nodes can be found here.
* Verify that the analyser is switched on and connected to the network by pinging it using
ping ctvr-analyser.cs.tcd.ie
* Use a VNC client to connect to ctvr-analyser.cs.tcd.ie
Remote control and IQ acquisition using Matlab
It is also possible to perform remote control and IQ acquisition using Matlab.
