 TR-4122B is a set of spectrum analyzers, signal sources, frequency, Sweep four functions as one integrated test instrument. It can measure the frequency range of 100KHz to 1500MHz, for broadband amplifiers and gain flatness measurement for television field strength measurements, the RF signal spectrum analysis, because the frequency of 8-bit display, you can screen read out with the cursor on the exact frequency value, which sets the spectrum analyzer with tracking generator output, so that the instrument functions are expanded. 

 Spectrum analyzer performance: 

 Frequency Range: 100KHz-1500MHz 

 Swath width: from 100MHz to each grid 2KHz. Step sequence followed by 1-2-5.
