Signal Hound offers a 30 day trial for their products. I have been looking at the BB60C for a while and finally picked one up. The first problem I ran into is it will not run on my laptop which is an i7 2630QM with a Fresco Logic FL1000 USB 3 controller. Basically the software crashes when changing settings. Stable just running swept.
The manual is not very comprehensive. The USB "Y" cable is very short (24").
Runs a bit on the warm side. I measured an increase of 13C for the outside case temperature (27 amb, 40C case).
There are a fair number of spurs in the 200 - 300KHz range (power supply perhaps). Spurs seen at every 10MHz to 100MHz. Above 100MHz, spurs at 160, 240, 320, 360, 370, 380..... 1200, 2400, 2560 Interesting behavior from 708 to 713 when span is set to 5MHz. Same form 728-733, 748-753, 768-773 ...
Tried a few different frequencies and the amplitude seems fair compared with HP 8660D. At 99MHz (away from spur), I measured the following:
0dB, -0.02
-10, -9.96
-20, -19.9
-30, -29.9
-40, -39.8
-50, -49.3
-60, -59.1
-70, -68.9
-80, -79
-90, -89
-100, -98.6
-110, -108.8
-120, -119
-130, -129
Phase noise at 1GHz, 100Hz from carrier is spec'ed at -70. Looks about -77 with the HP8660D(spec'ed to -95dB at 100Hz). 1MHz looks within spec.
All in all, looks like a nice setup. I just need to get a better PC to run it.
