Advantest U3771  Portable Spectrum Analyzer With Battery Pack

Optimal for Monitoring, Remote Control via a LAN

A 10/100BASE-T LAN port is provided as standard equipment, enabling remote control from a personal computer. The U3771/3772 can be installed at a remote-controlled station, such as an unattended, wireless transmission station, and signal output can be measured and observed through remote control and monitoring from a distant location.

Searching for the location of a fault in a coaxial cable

When used with its tracking generator option and the sample software for an external PC, the U3771/3772 can measure the distance to the failure point (open/short) in a coaxial cable. This application permits this distance to be measured from one end of the coaxial cable.

Evaluation of microwave oscillation circuits and microwave module characteristics

Using sample software on an external PC, the U3771/72 is an effective tool for evaluating phase noise characteristics of microwave oscillation circuits and microwave modules. Offset frequency from a carrier can be optionally set, making it easy to create a graph. Additionally, RMS jitter can be obtained from the power spectrum, simply by setting the frequency band.

High-Stability Frequency Reference Source OPT.20

Frequency of the high frequency signal was conventionally counted with a frequency counter. However, multi-carrier method is often employed for the recent communication system which uses high frequency signals which contains multiple frequency components, a frequency counter cannot count the frequency correctly. Therefore, the frequency counter of the spectrum analyzer attracts attention as an essential function. In a spectrum analyzer, just by pointing the marker at the spectrum separated as a sine wave of CW, not only the frequency counting but also faint signal level counting is possible. OPT.20 improves the aging stability of the standard oscillator which determines the frequency counter accuracy of a spectrum analyzer.

EMC Filter OPT.28

Option 28 adds 6 dB RBW CISPR bandwidths for EMI measurement of 200 Hz, 9 kHz, 120 kHz, and 1 MHz. A broadband sweep by the spectrum analyzer is very effective at measuring noise emitted from electrical devices. Installing OPT.28 allows measurement in CISPR-specified bandwidths. It enables simple, fast measurement using the Positive peak detector and Max Hold, which makes it effective at compensating for emitted noise. It guarantees an impulse bandwidth accuracy of 1 MHz. This capability conforms to the standard for noise measurement of 1 GHz or above.

2 Channel Input OPT.10

Two-channel input option (OPT.10) offers two independent lines of RF input. Various measurement conditions including measuring frequency and spans can be set independently for each RF input.

High-speed process by the parallel processing
