Differences
The few differences between the 33220A/33250A and Trueform Series generators that
might affect migration are listed below. Many of these differences improve the perfor-
mance of the Trueform Series generators relative to that of the 33220A/33250A function
generators.
Physical differences
– GPIB connectivity is optional on the 33600A Series.
– RS-232 connectivity is not available on the 33500B/33600A Series.
– The 33250A is physically deeper than the Trueform generators.
– Connectors are in different positions.
