README

pyB12MPS is a python package for interfacing with Bridge12 MPS.

The complete online documentation for the Bridge12 MPS is available here.

The complete online documentation for pyB12MPS is available here.

Requirements

• Python3 (>= 3.6)
• numpy, pySerial

Communicating with the Bridge12 MPS

First make sure the Bridge12 MPS is connected to the computer via a USB cable and the system is powered ON.

In a terminal window, start a python environment

python

import pyB12MPS

mps = pyB12MPS.MPS()

The MPS will reset and the python environment will hang until the MPS has initialized.

To close the MPS serial port:

mps.close()

Sending MPS Commands

Once the connection has been established, you can send commands to the MPS.

mps.freq(9.4) # set frequency to 9.4 GHz

mps.freq() # Query the microwave frequency in GHz

Example Script

import pyB12MPS
import time

mps = pyB12MPS.MPS()

# Number of Rx voltage points to acquire
pts = 10

# Time delay between measurements in seconds
dt = 0.5

rxVoltageList = []

for ix in range(pts):
    # delay
    time.sleep(dt)

    # Read MPS Rx diode voltage
    rxVoltage = mps.rxpowermv()

    # Print Rx voltage reading
    print('Rx Voltage: %0.01f'%rxVoltage)

    rxVoltageList.append(rxVoltage)

print('Rx Voltage Readings:')
print(rxVoltageList)
