Advantest Verigy V93000 V93k PS800 Board (E7945-66401)

The advantage of the old 6581 is that there is a reverse enginered schematics available, if needed for a repair.

As a downside the displays are often dim and a replacement is a bit tricky.

A know weak point for the 6581 is the rather large current spike from AZ switching – this can be an issue with some signal sources.

Another point is that ACAL may not be fully accurate for the highest resistor ranges.

So the specs there may be a bit overly optimistic.

Quite a few of the old meters also have a relay power saving mode not working right

that can cause some thermal EMF error that can effect the lower voltage ranges – this is fixable at least.

The 6581T tends to have a rather poor factory calibration that causes quite some INL error

– so while the ADC is essentially the same as with the full version, the linearity is not that great for the T version.

There may be ways to correct this, but it is extra effort and may need extra instruments (e.g. cal source).

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.

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.
