(Agilent E1445A

Commander)

These examples show you how to use the amplifier to add a DC offset to a signal supplied by the E1445A. In the first example, the E1446A is a servant to the E1445A. In the second example, the E1446A is a servant to the E1405 Command Module.

This program adds an 8V DC offset to a 0.4 Vpp E1445A signal. To maintain 0.4 Vpp at the output, the signal is attenuated by 20 dB at the amplifier input (Figure 2-1). The offset supplied by the E1446A DAC is added to the input signal and is amplified. Into 50W, the 0.4 Vpp signal is centered on 8V.

The steps of this program are:

1.Reset the E1445A AFG and E1446A amplifier.

*RST

2.Set the AFG frequency, function, and amplitude.
