Advantest BLD-024486 Processor PCB Card PLD-424486CC

The Q7750 is equipped with a variable wavelength light source.

The Q7750 is equipped with a variable wavelength light source that enables simultaneous measurement of transmission 

and reflection characteristics in the optical carrier frequency range by scanning a series of wavelengths (optical frequencies) (S21 and S11 as S-parameters).

The measurement parameters are shown in the table below. These parameters can be measured simultaneously in a single scan.

Outstanding signal purity

The U3661's local oscillator is equipped with a precision synthesizer that achieves a signal purity 

of -100 dBc/Hz (at frequencies ≤3.2 GHz and an offset frequency of 10 kHz). 

It meets a variety of needs, from adjacent channel leakage power measurements at radio facilities to microwave equipment evaluation.

Operation

In addition to amplifier analysis, a variety of display modes are available, such as

- Overlay display,

- Comparison with memory contents,

- Display of two independent graphs (split screen),

- Power meter function,

- Use of multiple markers,

- Normalized and direct readout of transmission loss and

- Automatic bandwidth analysis (e.g. measurement of half-value widths based on RMS and envelope methods),

- Curve fitting over the IEC/IEEE bus and many other features facilitate operation of the analyzer and simplify analysis.

Key Features

- Sensitivity -92 dBm

- Polarization correlation ±0.05 dB

- Resolution bandwidth accuracy ±2

- Power Measurement

- Pulsed light measurement

Average power

Digital mobile communication systems use modulation patterns that can handle signals with large amplitude variations.

Therefore, we have included an average power calculation function that allows power measurement of signals with amplitude variations.

Total Power

For spread spectrum signals used in CDMA or wireless LANs, the total power measurement function is essential. 

This function consists of two modes: a channel mode for measuring the in-band power specified in the measurement window,

and a total power mode for measuring the total power over the entire measurement span.

Internal or external triggering is possible.

Measurement time is 0.8 seconds for a span of 200 nm and varies with the span.

Broadband light sources with a resolution of 5 nm have the highest sensitivity, 

while narrowband light sources (lasers) can be reliably analyzed down to the noise level even with a narrow resolution bandwidth.

The normalization function combined with the white light source allows direct measurement of transmission and loss characteristics of filters and fibers.
