Advantest R3465

The Advantest R3465 spectrum analyzer goes beyond traditional spectrum analysis.

The 8GHz frequency response of R3465 provides coverage for a full range of digital radio frequencies.

The 6.5in. TFT color LCD display provides powerful support for multi-window operations.

It also incorporates a 15-degree adjustable tilt mechanism for easy viewing under a variety of lighting conditions.

The newly developed high-speed settling synthesizer significantly reduces blanking time for narrow-band sweep (span of 5MHz or less), thus enabling truly high-speed measurement.

A high-frequency sweep accuracy of 1% or less, frequency stability of 2 x 10-8 /day, and a built-in preselector starting from 1.7GHz permit harmonic measurements with a dynamic range of 100dBc.

In addition to these powerful spectrum analyzer functions, the R3465 unit also offers built-in modulation analysis for a variety of digital mobile communication standards.

The R3465 is a modulation spectrum analyzer which can analyze digital modulation such as measurement of modulation accuracy, transmission velocity, etc. in addition to conventional spectrum analyzing.

In 1.7 to 8.0 GHz range of the R3465, signals are added to the mixer via preselector and therefore the signals out of the measuring frequency range are suppressed by approximately 70 dB, relieving the distortion due to the signals out of the bandwidth.

The TRANSIENT mode is equipped which measures modulation accuracy of digital modulation signal/burst signal, OBW, ACP, etc. at high speed.

Parameter for standard measurements corresponding to various communication types (PHS/PDC/NADC) can be set automatically.

For proper level of measured signal, mixer input level must be -10 dBm or less. Exceeding this level caused input mixer to saturate or distort, leading to inaccurate measurement such as dropping of display level or increased spurious. Therefore, it is necessary to attenuate the signal to measure down to a proper level.

For base band of R3465, all input signals in the band are added to the mixer. Therefore, depending on the signals to measure, saturation or distortion may occur due to high level signals out of display screen.

A soft or damp cloth must be used to wipe any dirt of R3465 off. The usage of organic solvent must be avoided.
