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.
