Bill and Brad,

I might be interested, depending which exact plug-ins Bill has. I only have a 500-series scope, not a 560-series.

Bill, do you remember which model plug-ins you have?

thanks

Bill,

I would be interested in one of these instruments. It would partially fill the low-frequency hole left by my TinySA (which bottoms out at 100 kHz).

Looking at the TekWiki they show a picture of the 011 that has five knobs in a V-formation on the front panel, with V POS and VIDEO FILTER knobs flanking large CENTER FREQUENCY knob at the base of the V, the input BNC on the left flanking the two DISPERSION and RESOLUTION knobs in the middle of the V, and two knobs (ATTENUATOR and SCALE EXPANSION) at the top. The manual PDF, however, shows a distinctly different layout for the 011 front panel: six knobs in an inverted triangle, with the input BNC flanking the large CENTER FREQUENCY knob at the bottom vertex, an OSC OUT BNC flanking the two knobs in the middle (DISPERSION and RESOLUTION), and three knobs at the top (ATTENUATOR DB, ATTENUATOR RANGE-DB, and VERNIER GAIN), so it certainly appears that there were several different front panel layouts.

On further examination of the photo on the TekWiki it looks like the ATTENUATOR DB and ATTENUATOR RANGE-DB knobs from the illustration in the manual were combined into the ATTENUATOR knob at some point, so it seems like you may have examples of both versions.
