   ADVANTEST U3661   Description / Specification:    
ADVANTEST U3661 26.5 GHz Lightweight Microwave Spectrum Analyzer

The Advantest U3661 is a microwave spectrum analyzer with the measurement frequency range expanded to 26.5 GHz as well as the inherited features of the U3641 including the compact body, and battery operation. It has the weight and performance ideal for field as an indispensable instrument for maintenance inspection of microwave communication facilities. This portable analyzer provides enhanced basic performance with high-precision, high-stability measurements, a minimum sweep width of 1kHz by means of a synthesized local oscillator, and time domain measurements utilizing 50µs high-speed sweep. The U3661 operates not only on 100/200 VAC power but also on +10 to +16 VDC external power or on the battery pack; threeway power supply. It is designed to operate in any power source environment. The battery pack can be easily attached/ removed by a one-touch operation and rapidly recharged in one hour. It allows approximately 1.5 hour continuous operation on a full recharge, enabling logistically wide-ranging operation such as maintenance/installation work. Synthesizing of a local oscillator enables measuring the transmission characteristics (ACP, OBW) of narrow-band radio communication facilities. The sideband noise, -105 dBc/Hz or less, achieves the best performance in its class, enabling high-accuracy measurements even in field use. In Zero Span mode (fixed tuning mode without frequency sweep), the sweep time can be set up to 50µs. This makes it possible to observe TDMA waveforms for GSM, PDC and PHS, and to perform detailed analysis through magnified display of rising and falling burst waveforms. Specifications. Frequency range: 9 kHz to 26.5 GHz. Frequency read accuracy (start, stop, center frequency, marker frequency): ± (Reading of frequency × Frequency reference accuracy + 5% × Span + 15% × RBW + 8 GHz × N). Frequency span Range: 1 kHz to 26.7 GHz, 0Hz (zero span). Frequency span Accuracy: 5% of span. Amplitude Measuring range: +30 dBm to the average noise level. Maximum input level Preamplifier OFF (Input attenuator >= 10 dB): +30 dBm, 0 VDC max. Average indicated noise level: RBW 1 kHz, VBW 10 Hz, input ATT 0 dB, frequency bandwidth >= 1 MHz. Sweep time: 50 ms to 1000 s. Options. OPT20, High-stability reference source. OPT26, RBW 100 Hz, 300 Hz. OPT60, CDMA measurement. OPT72, TV image/sound demodulation. OPT74, Tracking generator. OPT78, Channel input setting.

Averaging
Averaging is a mathematical process to reduce the variation in a measurement by summing the data points from multiple measurements and dividing by the number of points summed.

Jitter
Jitter in technical terms is the deviation in or displacement of some aspect of the pulses in a high-frequency digital signal. Jitter is the time variation of a periodic signal in electronics and telecommunications, often in relation to a reference clock source. Jitter may be observed in characteristics such as the frequency of successive pulses, the signal amplitude, or phase of periodic signals. Jitter is a significant, and usually undesired, factor in the design of almost all communications links (e.g., USB, PCI-e, SATA, OC-48). In clock recovery applications it is called timing jitter.

Pulse Power
Pulse Power, the energy transfer rate is averaged over the pulse width. Pulse width is considered to be the time between the 50 percent risetime/falltime amplitude points. Pulse power averages out any aberrations in the pulse envelope such as overshoot or ringing.
