ATTEN AT5011A Spectrum Analyzer: Tracking generator NOT WORKING. Frequency range of 0.15MHz to 1050 MHz. The spectrum analyzer portion works perfectly. I purchased it new in April 2014 to tune duplexers and used it less than 10 times. I accidentally transmitted 5 watts into the tracking generator (TG) and likely fried the first attenuator: The attenuation knob is non-functioning anymore. The TG works but with about 10 dB attenuation. Being sold as a spectrum anaylzer only. It is comparable to the ATTEN AT5010 but with a partially functioning TG added. $400. I have all the original packaging, manual, and cables.
