Hello All,
New member here. I have a Type 1L10 Spectrum Analyzer plug-in that I've owned for several years. It's nice and clean, however the previous owner removed some parts for some reason. It was missing the 100 kHz crystal, the 49.3 MHz crystal, the 900 kHz crystal, and one of the SMA jumpers. I found something to use for everything except the 900.000 kHz crystal. I have looked EVERYWHERE. The Tektronix part number is 158-0021-00. I'm not real pleased with what I found for the 49.3 MHz crystal, so if someone knows where one of those is would be nice. That one is Tektronix part number is 158-0020-00 Thanks in advance, and I look forward to reading lots of good things on this forum.
