[Python] Stop PyVISA from writing to the console in Spyder

    I have some code which utilizes the PyVISA package to control a detector through USB. The code runs perfectly fine, but PyVISA dumps a bunch of debug information in the console which is making it difficult for me to print to the console to debug myself. Code and console printout below.

    My code:

    def pmt_onoff_test(gain_level = 0, offset_voltage = -0.009, lpfreq = 80000000):
    gain_voltage = PMT1_gain_levels['voltage'].iloc[int(gain_level)

    rm = pyvisa.ResourceManager()
    pmt1 = rm.open_resource(pmt1_address)

    pmt1.write("INST:SEL GAIN")
    pmt1.write("SOUR:VOLT %f" % gain_voltage)

    pmt1.write("INST:SEL OFFSET")
    pmt1.write("SOUR:VOLT %f" % offset_voltage)

    pmt1.write("SENS:FILT:LPAS:FREQ %f" % lpfreq)

    pmt1.write("SENS:FUNC:ON %s" % pmt2101_model)
    time.sleep(5)
    pmt1.write("SENS:FUNC:OFF %s" % pmt2101_model)

    rm.close()


    Console output:

    I tried searching the PyVISA API documentation for some option to turn off debug information but couldn't find anything. Does anyone have suggestions for suppressing this output in the console?
