Signal Characteristics:
Table 4-1 provides the connector pinouts for the User port connector.
The 25-pin User port on the RFG 1251 generator provides analog and digital signals for
control and monitoring of the generator functions. Figure 4-2 shows the electrical diagrams for
the interface circuitry in the generator. Table 4-1 provides descriptions of the signal types used
in the RFG 1251 generator.
5706058-A
25-pin, subminiature-D, shielded, female
Unless otherwise specified, all analog signals are 0 to 10 V, while
all digital signals are opto-coupled (digital inputs require 4 to 30 V
for a logic high, while digital outputs are open-collector signals
with return lines non-referenced to ground).
