Tektronix SW-503 400MHz sweep generator
$375 Negotiable
Rare Tektronix SW-503 400MHz RF sweep generator. Sweep widths 10/100/400MHz, adjustable. Marker spacing 1/10/50MHz. All the usual ins and outs: RF out 50 ohms, detector in, scope X and Y out, and auxiiliary RF out.
These were designed for the cable TV industry. It is possible but very fiddly to use them for VHF-FM IF alignment at 10.7MHz, and somewhat easier to use for VHF-FM RF alignment 88-108MHz, but these are not the recommended applications.
Pulled from working environment. Calibrated by owner (no certificate). This one has had the unobtanium 1-400 centre frequency control replaced by the same thing but reading 1-1000, so you have to divide your desired frequency by 0.4, or multiply by 2.5.
Usual TM500 broken corners on this one, please see photos. The scope photo shows the actual sweep (above) and markers (below) at the settings in the photo of the front, centre frequency about 10Mhz near the bottom of its range. Markers improve at higher frequencies.
PDF manual and service information available.
NOTE: This is a plugin for the TM500 mainframe system. A TM501/2/3/4/6 or TM515 mainframe is required. Does not operate standalone.
