Amplifier Block Diagram

Input

Figure 1-4 shows a block diagram of the Agilent E1446A Summing Amplifier/DAC.

The Agilent E1446A Summing Amplifier/DAC has two input channels that have identical input amplifiers with independently controlled input impedance and input attenuation. The input amplifier attenuators provide independent level control prior to the summing node. The attenuation can range from 0 to 31 dB in 1 dB steps. The input impedance can be set to 50, 75, or 1 M.

Output The output channels provide the amplifier with the capability to boost the power output of a low-power signal source, and to provide low-level differential output. The output channels are:

single-endedmain output or power amplifier.

differential (small signal) output; one inverting, one non-inverting.

Main Output The power amplifier sums the two input channels plus the output of a 16-bit offset Digital-to-Analog Converter (DAC) to obtain output levels of ±10 Vpeak into a 50or 75load on the single-ended output or ±20 Vpeak into high impedance. The voltage gain of the power amplifier is set at 10

(20 dB) into a matched load, and at 20 (about 26 dB) into a high impedance. To obtain the desired output, the output attenuation and the output impedance can be independently selected. The output impedance can be set
