Instrument Control

Instrument control classes are contained in the tam package. Here is a brief example illustrating the usage:

import sys
from tam import (
    InstrumentMgr, InstrumentInitializeException,
    UnknownInstrumentModelException
)

mgr = InstrumentMgr()
try:
    siggen = mgr.open_instrument('DSG815', 'TCPIP0::192.168.0.199::INSTR')
    sa = mgr.open_instrument('HP8560A', 18)
except InstrumentInitializeException as iie:
    print(iie.message)
    sys.exit(-1)
except UnknownInstrumentModelException as ume:
    print(ume.message)
    sys.exit(-1)

siggen.set_signal_output(1000, 0.0)
sa.measure_pwr(1000)

Available device models can be listed as follows:

from tam import manager
list(manager.INSTRUMENTS)
>>> ['SMHU58', 'HP8560A', 'HP11729C', 'DSG815', 'DSA815', 'DG4162',
'DDSGEN', 'PowerMeter']

rfblocks Based Instruments

• DDSGen
• PowerMeter
• SADisplay

Third Party Instruments

• DG4162
• DSG815
• SMHU58
• DSA815
• HP8560A

Middleware Classes

• InstrumentMgr
• GPIB
• VisaDevice

Adding New Instrument Models

Device models will fall into one of three categories depending on which type of instrument control they support:

list(manager.GPIB_MODELS)
>>> ['SMHU58', 'HP8560A', 'HP11729C']
list(manager.VISA_MODELS)
>>> ['DSG815', 'DSA815', 'DG4162']
list(manager.RPYC_MODELS)
>>> ['DDSGEN', 'PowerMeter']
