Holzworth

HS9000 Multichannel frequency synthesizer

class instruments.holzworth.HS9000(filelike)

Communicates with a Holzworth HS-9000 series multi-channel frequency synthesizer.

class Channel(hs, idx_chan)

Class representing a physical channel on the Holzworth HS9000

Warning

This class should NOT be manually created by the user. It

is designed to be initialized by the HS9000 class.

query(cmd)

Function used to send a command to the instrument while wrapping the command with the neccessary identifier for the channel.

Parameters:cmd (str) – Command that will be sent to the instrument after being prefixed with the channel identifier Returns:The result from the query Return type:str

recall_state()

Recalls the state of the specified channel from memory.

Example usage: >>> import instruments as ik >>> hs = ik.holzworth.HS9000.open_tcpip(“192.168.0.2”, 8080) >>> hs.channel[0].recall_state()

reset()

Resets the setting of the specified channel

Example usage: >>> import instruments as ik >>> hs = ik.holzworth.HS9000.open_tcpip(“192.168.0.2”, 8080) >>> hs.channel[0].reset()

save_state()

Saves the current state of the specified channel.

Example usage: >>> import instruments as ik >>> hs = ik.holzworth.HS9000.open_tcpip(“192.168.0.2”, 8080) >>> hs.channel[0].save_state()

sendcmd(cmd)

Function used to send a command to the instrument while wrapping the command with the neccessary identifier for the channel.

Parameters:cmd (str) – Command that will be sent to the instrument after being prefixed with the channel identifier

frequency

Gets/sets the frequency of the specified channel. When setting, values are bounded between what is returned by frequency_min and frequency_max.

Example usage: >>> import instruments as ik >>> hs = ik.holzworth.HS9000.open_tcpip(“192.168.0.2”, 8080) >>> print(hs.channel[0].frequency) >>> print(hs.channel[0].frequency_min) >>> print(hs.channel[0].frequency_max)

Type:Quantity Units:As specified or assumed to be of units GHz

frequency_max

frequency_min

output

Gets/sets the output status of the channel. Setting to True will turn the channel’s output stage on, while a value of False will turn it off.

Example usage: >>> import instruments as ik >>> hs = ik.holzworth.HS9000.open_tcpip(“192.168.0.2”, 8080) >>> print(hs.channel[0].output) >>> hs.channel[0].output = True

Type:bool

phase

Gets/sets the output phase of the specified channel. When setting, values are bounded between what is returned by phase_min and phase_max.

Example usage: >>> import instruments as ik >>> hs = ik.holzworth.HS9000.open_tcpip(“192.168.0.2”, 8080) >>> print(hs.channel[0].phase) >>> print(hs.channel[0].phase_min) >>> print(hs.channel[0].phase_max)

Type:Quantity Units:As specified or assumed to be of units degrees

phase_max

phase_min

power

Gets/sets the output power of the specified channel. When setting, values are bounded between what is returned by power_min and power_max.

Example usage: >>> import instruments as ik >>> hs = ik.holzworth.HS9000.open_tcpip(“192.168.0.2”, 8080) >>> print(hs.channel[0].power) >>> print(hs.channel[0].power_min) >>> print(hs.channel[0].power_max)

Type:Quantity Units:instruments.units.dBm

power_max

power_min

temperature

Gets the current temperature of the specified channel.

Units:As specified by the instrument. Return type:Quantity

channel

Gets a specific channel on the HS9000. The desired channel is accessed like one would access a list.

Example usage:

>>> import instruments as ik
>>> hs = ik.holzworth.HS9000.open_tcpip("192.168.0.2", 8080)
>>> print(hs.channel[0].frequency)

Returns:A channel object for the HS9000 Return type:Channel

name

Gets identification string of the HS9000

Returns:The string as usually returned by *IDN? on SCPI instruments Return type:str

ready

Gets the ready status of the HS9000.

Returns:If the instrument is ready for operation Return type:bool
