MHS5200 Function Generator

class instruments.minghe.MHS5200(filelike)[source]

The MHS5200 is a low-cost, 2 channel function generator.

There is no user manual, but Al Williams has reverse-engineered the communications protocol: https://github.com/wd5gnr/mhs5200a/blob/master/MHS5200AProtocol.pdf

class Channel(mhs, idx)[source]

Class representing a channel on the MHS52000.

property duty_cycle

Gets/Sets the duty cycle of this channel.

Units:

A fraction

Type:

float

property enable

Gets/Sets the enable state of this channel.

Type:

bool

property frequency

Gets/Sets the frequency of this channel.

Units:

As specified (if a Quantity) or assumed to be of units hertz.

Type:

Quantity

property function

Gets/Sets the wave type of this channel.

Type:

MHS5200.Function

property offset

Gets/Sets the offset of this channel.

The fraction of the duty cycle to offset the function by.

Type:

float

property phase

Gets/Sets the phase of this channel.

Units:

As specified (if a Quantity) or assumed to be of degrees.

class Function(*values)[source]

Enum containing valid wave modes for

sawtooth_down = 4
sawtooth_up = 3
sine = 0
square = 1
triangular = 2
property channel

Gets a specific channel object. The desired channel is specified like one would access a list.

For instance, this would print the counts of the first channel:

>>> import instruments as ik
>>> mhs = ik.minghe.MHS5200.open_serial(vid=1027, pid=24577,
baud=19200, timeout=1)
>>> print(mhs.channel[0].frequency)
Return type:

list`[`MHS5200.Channel]

property serial_number

Get the serial number, as an int

Return type:

int
