B.43 Magnet Power Supply Keithley 228A (Berlin W-Band)
Module name: keithley228a
Additionally required module: sr510,
sr530, sr810 or sr830 (to be
set via the configuration file for the device)
Description: Keithley power
supply 228A, used as sweep coil power supply for the Berlin W-band
spectrometer. In order to improve the current resolution an aditional
voltage source is needed. Currently this done via the DAC output
6 (can be changed by one of the functions) of the Stanford
Research lock-in amplifier SR510/SR530/SR810/SR830 (the corresponding
module must be listed before the power supply module). Alternatively,
after minor changes to the configuration file, also other lock-in
amplifiers can be used.
Please note: With this module the functions expect arguments in terms of the currents through the sweep coil, not in field units!
Controlled via: GPIB bus (IEEE 488).
In the GPIB configuration file use "KEITHLEY228A" as the device name,
'\n' or 0xa as the EOS character, set set-reos and
set-xeos to yes and set-bin to no.
