SSP-9081

Python control over Manson SSP-9081 Power Source

Installation

pip install .

Usage

Serial interface

import ssp_9081
from ssp_9081.interfaces import SSP_9081_Serial
from ssp_9081 import SSP_9081

com = SSP_9081_Serial('COM3')
power = SSP_9081(com)

power.setU(12.) # set voltage 12V
power.setOut(True) # turn it on

print(power.getUI())
print(power.getPower())

Script to control SSP_9081 via serial(USB) interfacessp9081 --off -u=12 --on:
will turnoff the output, set 12V and turn the power on

optional arguments:
  -h, --help            show this help message and exit
  -p PORT, --port PORT  Serial port name, default is taken from ENV_VAR
                        "SSP_9081"
  -u SETU, --setU SETU  Set Voltage (float value)
  -i SETI, --setI SETI  Set Current (float value)
  -on, --on             set to turn on the power, last action to execute
  -off, --off           set to turn off the power, first action to execute if
                        specified
  --waitU WAITU         wait for the setU action to be applied with timeout,
                        --waitU=0 to wait without timeout
  --setWaveForm SETWAVEFORM
                        waveform csv file: (step,voltage,time)
  --setWaveFormCycleNumber SETWAVEFORMCYCLENUMBER
                        Set the waveform cycle number amount of times given
                        waveform will perform cycleNum: 0 -> unlimited times
  --startWaveForm       start waveform
  --stopWaveForm        stop waveform
  --getU                print Voltage
  --getI                print Current
  --getOut              print if the power is on or off
  --hwversion           print version returned by SSP_9081

Example:

>> ssp9081 --setU=12 --on
setU(12.0V):  True
setOn:  True

>> ssp9081 --off --setU=6.5 --setI=2 --on
setOff:  True
setI(2.0A):  True
setU(6.5V):  True
setOn:  True

>> ssp9081 --getU
getU:  6.51

>> ssp9081 --getI
getI:  1.456

>> ssp9081 --hwversion
Version:  Rev1.2


>> ssp9081 --setWaveForm test.csv
setWaveForm:  [(True, None), (True, None), (False, None), (True, None), (True, None), (True, None), (True, None)]

>> ssp9081 --startWaveForm
setOn:  True #if power was off
setWaveFormOn:  (True, None)

WaveForm

CSV Format

step(1-10), voltage(0.0 - 36.40V), time(0s - 1200s)

Example:

1,14.0,0
2,3.8,5
3,4.0,10
4,12.0,10
5,12.0,20

Command: ssp9081 --setWaveForm example.csv --setWaveFormCycleNumber 1 --startWaveForm will trigger this profile in SSP9081

• Step 1: set 14V immidiately
• Step 2: set 3.8V immidiately
• Step 3: set 4V during 5 sec
• Step 4: set 12V during 10 sec
• Step 5: pause 12V for 10 sec
• Step 6: set 14V during 20 sec (falling to Step1)
• Switch off power (if --setWaveFormCycleNumber 1 is specified, otherwise continue to Step2)
