Additional Features: Frequency Range: 9 kHz to 8 GHz Signal Purity: 105 dBc/Hz 20 kHz Offset; 100 dBc/Hz 10 kHz Offset Total Level Accuracy: Maximum ±1.5 dB High-speed GPIB, Effective for System Applications High Speed Measurement: 20 Traces per Second 6.5-inch TFT Color LCD Built-in Frequency Counter Floppy Disk for Data Saving Large Numeric Display for Measurement Results (In Counter and Power Measurement Mode) Printer Port RS-232 Port VGA output 20 dB Preamp QP detector and EMC filters The Advantest R3162 Spectrum Analyzer offers wider dynamic range and lower 2nd and 3rd order distortion by improving 1 dB compression point. As a result of increasing the sweep repetition cycles by improving the synthesized local oscillator, 20 traces/second (typ.) data rewriting becomes possible, enabling far more real-time waveform measurement. Also, the high speed GPIB increases the throughput of automatic measurement on the R3162 . Internal automatic calibration function guarantees the total level accuracy of ±1.5 dB; level correction factor can be stored in the internal memory, DDS is employed to improve frequency reading accuracy, and frequency span error is lowered to less than 1%.
