Got my hands on an older Holzworth Instrumentation HS1001C second hand as a reference for some phase noise measurement stuff, and while the unit seems to be in fine shape, it wasn't shipped with any software. The Holzworth site doesn't have any download links and mentions contacting support for software, but they've been unresponsive (it's been a week and a half or so).
Does anyone have the GUI application or a suitable driver for this instrument that they can share? Is there another way to get a hold of the software? Because they don't list previous versions on their site, I haven't even been able to get a full datasheet/user manual for the HS1001C, but there is a promotional flier which lists a lot of relevant specs and the general operation seems like it should be very straight forward.
