Chroma.Source¶

Code author: Kevin Kennedy <protonyx@users.noreply.github.com>

Limitations¶

This driver does not include any of the device programming functionality, it is assumed that an automated program would be designed in a script that uses this driver.

class labtronyx.drivers.Chroma.Source.d_620XXP(resource, **kwargs)[source]¶

Driver for Chroma 6200P Series DC Power Supplies

disableRemoteInhibit()[source]¶: Disables the remote inhibit pin.

enableRemoteInhibit()[source]¶: Enables the remote inhibit pin. This behaves as an external ON/OFF control.

getCurrent()[source]¶

Get the output current level

Returns:	float

getCurrentRange()[source]¶

Get the configured output current range

Returns:	tuple (lower, upper)

getError()[source]¶

Returns the error message and code of the last error

:returns str

getProtection()[source]¶

Get the protection set points

Returns:	dict with keys [‘Voltage’, ‘Current’, ‘Power’]

getTerminalCurrent()[source]¶

Get the measured current from the terminals of the instrument

Returns:	float

getTerminalPower()[source]¶

Get the measured power from the terminals of the instrument

Returns:	float

getTerminalVoltage()[source]¶

Get the measured voltage from the terminals of the instrument

Returns:	float

getVoltage()[source]¶

Get the output voltage level

Returns:	float

getVoltageRange()[source]¶

Get the configured output voltage range

Returns:	tuple (lower, upper)

powerOff()[source]¶: Disables the output power connections.

powerOn()[source]¶: Enables the instrument to power the output

setCurrent(current)[source]¶

Set the output current level in Amps

Parameters:	current (float) – Current (in Amps)

setCurrentRange(lower, upper)[source]¶

Set the output current range

Parameters:	lower (float) – Minimum Current (in Amps) upper (float) – Maximum Current (in Amps)

setLocalControl()[source]¶: Sets the instrument in local control mode

setMaxCurrent(current)[source]¶

Set the maximum output current

Parameters:	current (float) – Current (in Amps)

setMaxVoltage(voltage)[source]¶

Set the maximum output voltage

Parameters:	voltage (float) – Voltage (in Volts)

setMeasurementAverage(avg)[source]¶

Set the number of readings to average.

Parameters:	avg (int) – Number of times to average (1, 2, 4 or 8)

setMeasurementAverageMethod(avg)[source]¶

Set the number of readings to average.

Parameters:	avg (str) – Method (‘FIX’ or ‘MOV’)

setMeasurementSpeed(speed)[source]¶

Set the reading speed of the voltage/current sensor

Parameters:	speed (int) – Samples per second (one of: 30, 60, 120, 240)

setProtection(voltage=None, current=None, power=None)[source]¶

Enable the protection circuitry. If any of the parameters is zero, that protection is disabled.

Parameters:	voltage (float) – OVP Setting (in Volts) current (float) – OCP Setting (in Amps) power (float) – OPP Setting (in Watts)

setRemoteControl()[source]¶: Sets the instrument in remote control mode

setSlewRate(voltage=None, current=None)[source]¶

Set the voltage and current rise/fall time of the power supply. Units are Volts per milliseconds.

Parameters:	voltage (float) – Voltage Slew rate (in V/ms) current (float) – Current Slew rate (in V/ms)

setVoltage(voltage)[source]¶

Set the programmed output voltage level

Parameters:	voltage (float) – Voltage (in Volts)

setVoltageRange(lower, upper)[source]¶

Set the output voltage range.

Parameters:	lower (float) – Minimum Voltage (in Volts) upper (float) – Maximum Voltage (in Volts)
