but the need for it is being overtaken in the latest models, where
blindingly fast digitising rates of 1Gs/s and above make it
redundant.
Figure 7.5
The Gould model 840 four channel high resolution digital storage
oscilloscope features a 1MHz bandwidth in 12 bit resolution mode
with, unusually, an anti-alias filter selected in accordance with the
timebase setting. In 8 bit mode the maximum single shot sample rate is
l OOMs/s, or equivalently 2.5Gs/s in repetitive mode, giving a
150MHz bandwidth. In addition to internal RAMDISK, there are floppy
or hard disk or memory card options. (Reproduced ...
