It does and I've downloaded copy but have yet to find time to hook everything up.

Looks very impressive though

Some info:

This is still the first version and there are some bugs, obviously. Also, I want to increase the functionality. Unfortunately I have had zero time for my hobbies in the past weeks.

In order to get the software working, the following is needed:

- CMU200 or CRTU with firmware v5.20 if serial connection is to be used - not tested with older firmware releases, but it seems that only v5.xx offers 115200 baud
- Keysight Connection Expert 2018: some users reported that it doesn't run with older versions. I don't know, because I only tried this version.
- Recommened: Agilent GPIB/USB interface (I ordered a "refurbished" one from China through eBay and it cost me around 80 Euro plus 60 Euro for customs).
- You need to setup remote connection on the CMU200/CRTU: test it with Keysight Connection Expert 2018. If it works here, it should work with my software.
- To run my software, you need a (free) activation code.

Regards,
Vitor

- Is it possible to set a ref -> pk  to a negative peak
- Can I change the power measure form dbm to watt

Check the list of GPIB commands. There are a couple of funtions and settings that are not accesible with the front panel controls. If it isn't there, it is not possible.

- Is it possible to make a print screen save it a usb stick

No. MS-DOS does not support any USB at all. There is a USB to PS/2 keyboard emulation in the BIOS, therefore an USB keyboard will work, but that is the only device type supported.

I have the Keysight 2017 software suite on a PCI based PC with a PCI GPIB card, I'm hopeful it will work with that.

CMU Base is 5.21

I'll dig out the PC and cables one evening next week and request a code, thank you for all your hard work.

Thanks all for your answers.

@Vitor
Looks great :-)
But do I need also OPSW v5.x installed? You have this mention on your blog. But not here on your post

OPSW v5.x is the DOS Software that runs on the CMU200 and CRTU.

I noticed that v3.x has only baud rates up o 19200, which is much too slow.
With v5.x you get 115200 baud, which is slow, but works.

Using the GPIB/USB interface you get 1.5MBit/s and thus you get a pretty fast refresh rate on the PC.

Vitor
