Advantest U4342

The Advantest U4342 is a U4941 series Spectrum Analyzer with a tracking generator. A tracking generator is a device that generates signals of the same frequency as the sweep frequency of a spectrum analyzer.

A tracking generator allows the measurement of filters or amplifiers.

The U4941 series field analyzer is a very portable RF field analyzer, that has been developed to be used for maintenance inspections in locations away from the lab bench and often out of doors, in the field.

Even though the analyzer is small and light in mass, it has a color LCD display. To further increase portability there are three power supply choices: a removable battery, AC/DC Adapter or an external DC supply.

The analyzer has a newly added MEASURE function that makes possible the measurements required by all types of applications without the need of any extra calculations.

This new function is added to the previous functions such as COUNTER, X dB DOWN, etc. Beside, using the internal preamplifier, an easy operation can be made to obtain an high-sensitive measurement or an AM modulation accuracy without the need of any extra calculations.

Remote control via either RS-232 or GPIB is possible. There are two slots for memory cards meeting the JEIDA Ver. 4.1 and the PCMCIA Release 2.0 specifications.

The analyzer was designed for use in outdoor settings. Even so, if it is used in situations that are outside the limits indicated below then you may not be able to obtain completely satisfactory performance.

The analyzer should only be operated at temperature between 0 to 50 deg C. The relative humidity should be below 85%. Even within this temperature range, quick changes in temperature can lead to moisture condensation. If that happens please avoid using the analyzer unit it is dry inside again.

Avoid using the analyzer anywhere that there is much vibration, or where corrosive gases are present.
