Holzworth¶
HS9000
Multichannel frequency synthesizer¶
- class instruments.holzworth.HS9000(filelike, *args, **kwargs)[source]¶
Communicates with a Holzworth HS-9000 series multi-channel frequency synthesizer.
- class Channel(hs, idx_chan)[source]¶
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)[source]¶
Function used to send a command to the instrument while wrapping the command with the neccessary identifier for the channel.
- recall_state()[source]¶
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()[source]¶
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()[source]¶
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)[source]¶
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
- property frequency¶
Gets/sets the frequency of the specified channel. When setting, values are bounded between what is returned by
frequency_min
andfrequency_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:
- Units:
As specified or assumed to be of units GHz
- property frequency_max¶
- property frequency_min¶
- property output¶
Gets/sets the output status of the channel. Setting to
True
will turn the channel’s output stage on, while a value ofFalse
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:
- property phase¶
Gets/sets the output phase of the specified channel. When setting, values are bounded between what is returned by
phase_min
andphase_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:
- Units:
As specified or assumed to be of units degrees
- property phase_max¶
- property phase_min¶
- property power¶
Gets/sets the output power of the specified channel. When setting, values are bounded between what is returned by
power_min
andpower_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:
- Units:
instruments.units.dBm
- property power_max¶
- property power_min¶
- property 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:
- property name¶
Gets identification string of the HS9000
- Returns:
The string as usually returned by
*IDN?
on SCPI instruments- Return type:
