Simulate Transmitter Function
To verify the simulate transmitter function (accessed through dc current source function):
1. Connect the UUT, 8508A, and 5522A as shown in Figure 7. The 5522A is used
as a stable dc voltage source. Its value is not critical, and a different dc source
such as a battery can be used if necessary.
2. Set the 8508A to DC Current .
3. Set the UUT to the [mA Source] function and then select Simulate Transmitter.
4. Set the UUT source value to 4 mA.
5. Set the 5522A to output 8 V dc.
6. See if the value shown on the 8508A is in the range shown in Table 10.
7. Change the UUT source value to 22 mA and examine the results again in Table 10.
8. When you complete the test, set the 5522A to STANDBY and push on the
UUT two times to turn the source function off. This conserves battery life.
