   ADVANTEST U3641   Description / Specification:    
ADVANTEST U3641 3 GHz Lightweight Microwave Spectrum Analyzer

The Advantest U3641 is a 3-GHz synthesized spectrum analyzer ideal for field use. With a lightweight, compact size and three-way power supply including battery operation, the U3641 has been designed specifically for field installation and maintenance applications. In addition, with the inclusion of a synthesized local oscillator, the U3641 allows high-precision and high-stability measurements with a minimum resolution bandwidth of 100 Hz. A fast zero span sweep speed of 50 µs allows characterization of burst signal rising and falling edges and the measurement of power during on and off periods. The U3641 portable analyzer can be used for maintenance on various aspects of CATV and PHS/PDC. The U3641 operates not only on 100/200 V AC power but also on +10 to +16 V DC power or the battery pack. The battery pack can be easily attached or removed. It allows 1.5 hour continuous operation at a full charge, making it easier to perform logistically wide-ranging measurements such as maintenance and installation work. Rapid 1 hour battery charging time. The U3641 calculates the bandwidth for the specified power ratio from measured spectrum data and then displays it with the marker. In addition, it displays the occupied frequency bandwidth (OBW) and carrier frequency (FC) at the upper left portion of the screen. The ratio of the obtained power to the total power can be specified in the range from 10.0 to 99.8%. Specifications. Frequency range: 9 kHz to 3 GHz. Frequency read accuracy (start, stop, center frequency, marker frequency): ± (Reading of frequency × Frequency reference accuracy + 5% × Span + 15% × RBW + 10 Hz). Frequency span Range: 1 kHz to 3.2 GHz, 0Hz (zero span). Frequency span Accuracy: <= ±5% of span. Amplitude Measuring range: +20 dBm to displayed Average Noise Level. Maximum input level Preamplifier OFF (Input attenuator >= 10 dB): +27 dBm, ±50 VDC max. Sweep time: 50 ms to 1000 s. Dynamic Range Displayed Average: (RBW 1 kHz, VBW 10 Hz, Input atten 0 dB, f =1 MHz). Options. 15, Controller option. 20, High-stability reference option. 26, RBW 100Hz, 300Hz option. 72, TV demodulation option. 74, Tracking generator option. 78, Channel input setting option.

*This is a Web introductory price for one calibration of the ADVANTEST U3641. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

dBc
dBc (decibels relative to the carrier) is the power ratio of a signal to a carrier signal, expressed in decibels. If the dBc figure is positive, then the relative signal strength is greater than the carrier signal strength. If the dBc figure is negative, then the relative signal strength is less than carrier signal strength.

Noise Density
Noise Density is the amount of noise within a defined bandwidth, usually normalized to 1 Hz.

Spurious Signals
Spurious signals are undesired signals. They can be considered in two classes. They can be stationary; their frequency and amplitude do not change significantly, or non-stationary, where the frequency and/or amplitude change significantly over short time periods.
