Naive EPICS IOC for WaveStation 3122

Limitations

• No Status reading from WaveStation 3122, the current implementation is write commands to the device.

Support Waves

• BSWV (SINE, SQUARE, RAMP, PULSE, NOISE, ARB, DC) : all parameters can be defined, however, according to the wave type, invalid parameters will be disabled automatically. The all parameters should be defined first, before send the command to the wave station. If one would like to use, please look command orders at cmds file.

• BTWV : Due to the vendor SCPI command limitation, we cannot set the entire parameters (BTWW and its carrier Waveform). We have to define the Carrier Waveform parameters first, then we have to define BTWV parameters.

Warning

Requirements

• Asyn should be compiled with DRV_USBTMC=YES, which can be enable in (ASYN)/configure/CONFIG_SITE (libusb-1.0 or libusbx is needed according to the Linux distribution)

• Add RELEASE.local as follows:

EPICS_BASE=/home/jhlee/epics_env/epics-base
ASYN=${EPICS_MODULES}/asyn

• Optional Modules : (iocStats, autosave)

Optional

DEVIOCSTATS=${EPICS_MODULES}/iocStats AUTOSAVE=${EPICS_MODULES}/autosave

• UI is for latest CS Studio with Display Builder (not BOY) in WS3122App/op
