# Requirements
numpy  
pyvisa  
visa backend (e.g.: ivi, pyvisa-py, R&S ...)

# Installation

```
git clone https://github.com/mathieu-couillard/keysight_E5071C.git
cd keysight_E5071C
pip install .
cd ..
rm -fr keysight_E5071C
```

# Usage
This driver provides most commands to scan a frequency range and collect traces on any of channels. Commands can change settings individually or change many parameters related to a specific feature (e.g.: set_trigger(), set_averaging(), set_freq_axis(), set_response_axes()) which takes the paramters as arguments, or any arbitrary set of parameters using the set_paramters() which takes as dictionary as an argument(Look at this function to find the dictionary keys).

You can print every command sent using the verbatim=True when instantiating.

Methods with write and query will default to the query when no argument is given.

```
vna.freq_center() # get center frequency
vna.freq_center(5e9) # set center frequency to 5 GHz
```

Two ways to use the code are shown, one shorter:
```
################
# Create object/Connect to device.
################
rm = visa.ResourceManager('@py')
addr = '192.168.0.117'
vna = E5071C(addr)

vna.set_freq_axis(start=1, stop=2, point=1001, bandwidth=1000, sweep_type='lin')
vna.set_set_response_axes(trace_formates=['mlog', 'phase', 'plot'], delay=1, phase_offset=180, Spar='S12')
vna.set_averaging(state='off', count=0)
vna.set_trigger(source='bus', averaging=0, initiate=True)

vna.trigger_now()
data = vna.read()
print(data)
```

Another longer, where each parameter is individually set:
```
################
# Create object/Connect to device.
################
rm = visa.ResourceManager('@py')
addr = '192.168.0.117'
vna = E5071C(addr)
################
# Set up parameters related to frequency scan.
################
vna.freq_start(1) # 1GHz
vna.freq_stop(2) #2GHz
vna.points(1001)
vna.bandwidth(1000)
vna.sweep_type('lin')
################
# Set up trace related commands. Channel related commands are similar.
################
vna.traces_number(3)
vna.active_trace(1)
vna.Format('mlog')
vna.Spar('S12')
vna.delay(1)
vna.phase_offset(180)
vna.active_trace(2)
vna.Format('phase')
vna.Spar('S12')
vna.active_trace(3)
vna.Format('Plog')
vna.Spar('S12')
vna.delay(1)
vna.phase_offset(180)
################
# Set up averaging parameters. Don't forget to set the "vna.trigger_averaging(True)" when using averaging
################
vna.average_state(False)
vna.average_count(0)
################
# Set up averaging parameters.
################
print(vna.trigger_source('bus'))
print(vna.trigger_averaging(False))
print(vna.trigger_initiate(True))
################
# Read the data on the screen
################
print(vna.trigger_now())
print(vna.freq_read())
print(vna.trace_read(1)[0])
print(vna.trace_read(2)[0])
data = vna.trace_read(3)
print(data[0])
print(data[1])
