PROTOCOLS > SCPI

📄 IDN

Query a device's identity through the universal *IDN? SCPI command.

📄 MEASURE VOLTAGE

Query an instrument's measured output voltage, such as a DMM or power supply.

📄 SCPI WRITE

Write a SCPI command to a connected bench-top instrument and return the result.

InstrumentKit

To connect to a HS 9008B Frequency synthesizer using Instrumentkit, you can use the following Python script:

import instrumentkit as ik

# Connect to the HS 9008B Frequency synthesizer
hs = ik.holzworth.HS9000.open_tcpip("192.168.0.2", 8080)

# Access the channels and retrieve their frequency
for channel in hs.channel:
    print(channel.frequency)

# Access the channels on the HS 9008B
channel_1 = hs.channel[0]
channel_2 = hs.channel[1]

# Get the frequency of channel 1
frequency_1 = channel_1.frequency
print(f"Frequency of channel 1: {frequency_1}")

# Set the frequency of channel 2 to 1 GHz
channel_2.frequency = 1 * ik.units.GHz

# Get the power of channel 2
power_2 = channel_2.power
print(f"Power of channel 2: {power_2}")

# Turn on the output of channel 1
channel_1.output = True

# Check if the HS 9008B is ready
is_ready = hs.ready
print(f"Is HS 9008B ready: {is_ready}")

This script imports the instrumentkit module as ik and then uses the open_tcpip method of the HS9000 class to connect to the HS 9008B Frequency synthesizer at the specified IP address and port number.

After connecting, you can access the channels of the synthesizer using the channel property of the HS9000 object. In the example script, it loops over all the channels and prints their frequencies.

It then performs various operations such as getting and setting the frequency and power of the channels, and turning on the output of a channel. Finally, it checks if the synthesizer is ready for operation.

Note: Make sure to replace "192.168.0.2" with the actual IP address of your HS 9008B Frequency synthesizer and 8080 with the appropriate port number.
