Generating and Amplifying Sine Waves
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 are a of
the E1405 Command Module.

This program uses the E1446A to amplify a 2 Vpp E1445A AFG signal to
14.15 Vpp. Since the intended output amplitude and the input amplitude are
known, the amount of attenuation (0 - 31 dB attenuator) is de te r mi ne d a s:
attenuation(dB) = 20 LOG (Vo/(Vi * 10))
where Vo is the output amplitude and Vi is the input signal ampl itude (Vo
and Vi units (Vpp, Vp) must be the same). Thus,
attenuation(dB) = 20 LOG (14/20) = -3 dB
The (main) output of the AFG is connected to ’Input 1’ of the amplifie r .
The steps of this program are:
1. Reset the E1445A AFG and E1446A amplifier.
*RST
2. Set the AFG frequency, function, and amplit ude.
