The [http://webstore.rohde-schwarz.com/us/hamegr-hmo2024.html Hameg HMO2024] is a USB-/RS232-based, 4-channel oscilloscope with an analog bandwidth of 200MHz and 2GS/s sampling rate.

See [[Hameg HMO2024/Info]] for more details (such as '''lsusb -v''' output) about the device.

== Protocol ==

The Hameg HMO series of scopes use [[IEEE-488|SCPI]] as the communication protocol.

== USB connection on OS X ==

To talk to the device over USB on OS X you need to ensure the HO720 interface card of the scope enumerates as a serial port. This does not happen automatically as the device ID of the HO720 card is not registered in the list of 'known devices' of the OS X FTDI driver.

To ensure you can communicate to the device, first install the [http://www.ftdichip.com/Drivers/VCP.htm - FTDI VCP driver for OS X].

Then, follow the instructions [https://rowley.zendesk.com/entries/109069-getting-jtag-and-serial-port-to-work-under-mac-os-x-using-a-luminary-ftdi-target-interface here] and add the following section to the Info.plist:

<nowiki>
<key>HamegScope</key>
<dict>
<key>CFBundleIdentifier</key>
<string>com.FTDI.driver.FTDIUSBSerialDriver</string>
<key>IOClass</key>
<string>FTDIUSBSerialDriver</string>
<key>IOProviderClass</key>
<string>IOUSBInterface</string>
<key>bConfigurationValue</key>
<integer>1</integer>
<key>bInterfaceNumber</key>
<integer>0</integer>
<key>idProduct</key>
<integer>60786</integer>
<key>idVendor</key>
<integer>1027</integer>
</dict></nowiki>

Connect the cable, power on the scope, ensure the USB interface is enabled under Setup > Interface on the device. A new serial device will be generated and you should be able to get the device info with:

$ '''sigrok-cli --driver hameg-hmo:conn=/dev/cu.usbserial-xxxxyyyy --scan'''
