General description of the
used ADVANTEST R3162
for sale.
The Advantest R3162 is a 8 GHz portable spectrum analyzer which realizes basic functions adaptable to various measurement needs. It can be used as dedicated measuring instrument for diversified applications, such as cable TV, EMC measurement and digital mobile communications. The 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%. As a result of increasing the sweep repetition cycles by improving the synthesized local oscillator, 20 cycle/s (typ.) of trace data rewriting becomes possible, enabling far more real-time waveform measurement. High speed GPIB increase, the throughput of automatic measurement, thus saving valuable time. For EMI precompliance measurement, 6-dB bandwidth filters for 9 kHz, 120 kHz and 1 MHz as well as QP detector are equipped as standard. Optional 200 Hz narrow band-pass filter can be added. For high-speed time domain measurement function which is indispensable for mobile communications, optional 50 µs sweep is effective. For power measurement, AVE. POWER and TOTAL POWER processing functions are provided. Counter function, ACP, OBW, dBc/Hz, %AM and many other functions are provided for various measurement purposes. The internal preamplifier is equipped as standard. The high-resolution, 6.5-inch TFT color LCD realizes easy-to-see display of data. Display data is output through the VGA video output on the rear panel and can be output to external monitor. Specifications. Frequency range: 9 kHz to 8 GHz. Frequency reading accuracy (Start, stop, center frequency, marker frequency): ±(Reading of frequency × Frequency reference accuracy + Span × 1% + Resolution bandwidth × 15% + 60 Hz). Frequency span Range: 1 kHz to 8 GHz, 0Hz (Zero span). Frequency span Accuracy: <= ± 1%. Resolution bandwidth (3 dB) Range: 1kHz to 3MHz, 1-3-10 sequence, 30 Hz to 300 Hz (Option). Measuring range: +30 dBm to the average of displayed noise level. Maximum input level (Input ATT >= 10 dB) Preamplifier OFF: + 30dBm, ± 50VDC max. Sweep time: 20 ms to 1000 s, 50 µs to 1 s (Option29, Zerospan). Options. OPT.20 High-stability frequency reference. OPT.27 Narrow-band resolution bandwidths. OPT.29 Time-domain high-speed sweeps. OPT.74 Tracking generator. OPT.73 Wide-range FM demodulation.
