Setting the Input Impedance
The examples in this section show you how to amplify a sine wave
generated by the Agilent E1445A. In the first program, the E1446A is a
servant of the E1445A AFG. In the second program, the E1446A amplifies
the signal from the E1445A, however; the E1446A is in the servant area of
the E1405 Command Module.
Setting the Input
Impedance
(Agilent E1445A
Commander)
This program sets the E1446A’s input impedance to match the output
impedance of the E1445A. The signal supplied by the E1445A is a 1 Vpp, 2
MHz square wave. The signal is amplified to 6.3 Vpp. Again, when the
intended output amplitude and the input amplitude are known, the amount of
attenuation (0 - 31 dB attenuator) is determined by:
