Advantest R3273

The Advantest R3273 is high-performance multifunction spectrum analyzers with all the basic functions necessary to meet the demand for wider frequency range and a higher C/N ratio for next-generation digital mobile communications.

The R3273 offers a Resolution bandwidth of 10MHz enabling accurate analysis of the rise and fall characteristics of high-speed amplitude modulated signals. The analog RBW extends down to 10Hz providing wide dynamic measurement.

Since the R3273 also support the digital resolution bandwidth (RBW) from 1 Hz to 100 Hz, they are suitable for high-resolution measurement.

To maximize the dynamic range of input signal amplitude, the R3273 have inputs with low distortion characteristics and reduced average noise levels. A wide dynamic range of measurement of -145dBc/Hz (at 2GHz, typical) with a 0dBm signal input.

Two-signal 3rd order inter-modulation distortion is essential for evaluating RF modules and wireless transmission devices. To provide this function the spectrum analyzer itself must have a low modulation design. The R3267 offers a high performance of -90dBc or less in the 1.6GHz to 8GHz range.

The R3264/3267/3273 support both spectrum analysis and modulation analysis in a single unit. In addition to major existing mobile communication standards, the R3264/3267/3273 can also support advanced standards such as W-CDMA/3GPP and cdma2000.

The advanced RF technology of ADVANTEST enables signal purity of -145 dBc/Hz (at 2GHz band, 5MHz offset, typical value). -145dBc/Hz (typ.) dynamic range can be measured within a 2GHz band.

Offering the highest basic functionality in their class, the R3264/3267/3273 ensure an ACP dynamic range of 70dBc or more (typ.) in W-CDMA ACP measurement.

These spectrum analyzers offer high performance for 2-signal 3rd order inter-modulation distortion, the R3267 delivering 90dBc or more in the 1.6 to 8GHz band. This makes them ideal for evaluating inter-modulation in transmission amplifiers and so on.

The R3264/3267/3273 feature high-speed transient signal analysis in the time domain sweep with a high speed of 1µs/ and a 10MHz IF bandwidth filter.

The spectrum analyzer can calculate the bandwidth of a specified power ratio from measured spectrum data and display the OBW. A frequency span accuracy of 1% or better enables highly accurate OBW measurement. Automatic measurement of harmonics is possible simply by inputting the frequency of the fundamental waveform and the order of the harmonic you want to measure.

The R3264/3267/3273 have a built-in power calculation function for burst signals with large amplitude variations typical of PDC and PHS, and for wide frequency range signals such as CDMA and OFDM. Measurement accuracy can be increased by executing PBW Cal. to calibrate the pass band characteristics of the IF band filter.

A wide band spurious search can require a long time for measurement, but this time can be dramatically reduced by running the spurious search using a sweep table corresponding to known spurious map. The R3264/3267/3273 allow you to create up to
10 tables of sweep start and stop frequencies.

The R3264/3267/3273 have a two-trace display function, and POSI, NEGA or SAMPLE detector modes can be specified separately for each trace. In addition, both traces are sampled simultaneously, allowing true simultaneous measurement of two traces. For example, it is possible to measure the peak factor by simultaneously sampling the POSI peak and AVE power.

The R3273 can be used with applications ranging from research and development of communication devices and modules to production line and deployment testing of communication infrastructure.
