[time-nuts] Seek info: R&S Harmonic Filter ATS-0W - Unit

[cfo]

Fellow time-nuts

I just got a HP 8594E SA 
I know it's not t-nut grade , but it was what i could afford.

HP 8594E Spectrum Analyzer 9KHz til 2,9GHz
- option 004 = Precision Frequency Reference
- option 010 = Tracking Generator 9KHz til 2,9GHz
- option 041 = GPIB interface + Parallel Printer Interface
- option 101 = Fast Time Domain Sweeps and Analog + Display
- option 105 = Time-gated Spectrum Analysis
- option 130 = narrow resolution bandwidths
And a 85630A - Scalar Transmission/Reflection test set

And i wanted to get some filters.

So i just bought/won a: 
Rohde & Schwarz
Harmonic Filters ATS-0W - 19" unit
model 1000.1755.02

I can't find any info at all on the net , and was wondering if anyone 
here had some info , especially about the GPIB (programming) and TTL plug 
on the backside.

TIA
