Programming the Amplifier

Base + 0C16

Bits 10 - 9: Input 1 impedance

Bits 2 - 1: Input 2 impedance

Figure C-2 is a block diagram of the Agilent E1446A Summing Amplifier/DAC. The diagram shows the portions of the summing amplifier/DAC configured with register-based programming. The following information covers the sequence used to program the amplifier.

Base + 0816

Bits 15 - 0: DAC control code

Base + 0A16

Bits 7 - 6: 0 / -20dB attenuation

Bit 5: ’Main’ Output impedance

Bit 4: ’Main’ output enable

Base + 0A16

Base + 0C16

Bits 15 - 11: Input 1 attenuation

Bits 7 - 3: Input 2 attenuation

Bits 3 - 2: output impedance of non-inverting and inverting differential output
