Rigol

Generic interfaces for instrumentation

Some background in French in GLMF 124

GPIB

Aka IEEE-488, a standard interface bus, requires an adapter on Rigol instruments and PC so we'll ignore it.

USBTMC

USBTMC is a protocol built on top of USB that allows GPIB-like communication with USB devices. From the user's point of view, the USB device behaves just like a GPIB device. See more on NI site.

VXI-11 RPC

VXI stands for VME eXtensions for Instrumentation

VXI-11 is a TCP/IP instrument protocol specification defined by the VXIbus Consortium. Since LXI instruments are based on Ethernet, the TCP/IP interface allows you to communicate with an LXI instrument using the VXI-11 interface.

Generic software for instrumentation

There are different standard APIs/layers to talk to a compatible device:

LXI – LAN Extensions for Instrumentation

See https://lxi.github.io/ and https://github.com/lxi/lxi-tools

git clone https://github.com/lxi/liblxi.git
cd liblxi
./autogen.sh
./configure
make
sudo make install
cd -
git clone https://github.com/lxi/lxi-tools.git
cd lxi-tools
./autogen.sh
./configure
make
sudo make install
sudo ldconfig

VISA – Virtual Instrument Software Architecture

• http://pyvisa.sourceforge.net/

apt-get install vish python-pyvisa python3-pyvisa

IVI – Interchangeable Virtual Instrument

• https://github.com/python-ivi/python-ivi not tested, seems not to support these Rigol devices

Sigrok

Debian version is too old to communicate with Rigol latest fw, so let's install it from git repo:

sudo apt-get install git-core gcc g++ make autoconf autoconf-archive automake libtool pkg-config libglib2.0-dev libglibmm-2.4-dev libzip-dev libusb-1.0-0-dev libftdi-dev check doxygen python-numpy python-dev python-gi-dev python-setuptools swig default-jdk libieee1284-3-dev libqt4-dev libboost-test-dev libboost-thread-dev libboost-filesystem-dev libboost-system-dev libqt5svg5-dev

DS1054Z Oscilloscope

• 1GSa/s, 24MS of capture when using one single channel
• 500MSa/s, 12MS of capture when using two channels
• 250MSa/s, 6MS of capture when using three or four channels

Using means displaying or using as trigger !

Hacks

• ./riglol DS1ZA181234567 DSFR => DS1104Z

• Fan is moderately noisy, someone proposed to [changing fan: https://www.youtube.com/watch?v=taLTQsWEEqc replace it (youtube)] with a Gelid Silent 5
  • I've still some doubts, imho the noise comes from air flow in the box itself, not much from fan, so less noise means less air flow...
  • update: I did the change and I highly recommend the operation! It's much silent now! Vcc on middle cable, GND on cable with text.

python OscScreenGrabLAN.py csv 192.168.1.60

ds1054z Python library

pip install ds1054z[savescreen,discovery]

Sigrok

sigrok-cli

sigrok-cli -d rigol-ds:conn=tcp-raw/192.168.1.60/5555 --scan
The following devices were found:
rigol-ds - Rigol DS1104Z 00.04.04.SP3 with 4 channels: CH1 CH2 CH3 CH4

sigrok-cli -d rigol-ds:conn=tcp-raw/192.168.1.60/5555 -O analog --frames 1

Trying other outputs seems bogus...

sigrok-cli -d rigol-ds:conn=tcp-raw/192.168.1.60/5555 -O wav --frames 1 -o /tmp/wav

=> ok but surrounded "FRAME-BEGIN\n" "FRAME-END", workaround:

sigrok-cli -d rigol-ds:conn=tcp-raw/192.168.1.60/5555 -O wav --frames 1 |tail -c +13|head -c -10 > /tmp/1.wav

sigrok-cli -d rigol-ds:conn=tcp-raw/192.168.1.60/5555 -O csv --frames 1

=> ok but mixed with analog, workaround:

sigrok-cli -d rigol-ds:conn=tcp-raw/192.168.1.60/5555 -O csv --frames 1 |sed '/^$/,/FRAME-END/d' > /tmp/1.csv

Other outputs (binary, hex, ...) all produce the analog output

pulseview

On HiDPI screen:

QT_AUTO_SCREEN_SCALE_FACTOR=1 pulseview

It seems it acquires only the screen size? How to increase window to the internal 24M?
