Secondary GPIB Address : Determined by dividing the logical address of the device by 8. If the amplifier is used with the Agilent E1445A, the secondary address is the E1445A logical address/8. If the amplifier is used with the Agilent E1405/06 Command Module, the secondary address is the E1446A logical address/8. Agilent E1445A AFG An example of the GPIB address in an BASIC statement when the amplifier is a servant of the Agilent E1445A is: OUTPUT 70910;"SOUR2:VOLT:OFFS 3" Where: Interface Se

Using an Embedded The Agilent E1446A Summing Amplifier/DAC can be programmed across the VXIbus backplane (select code 16) from an embedded controller, such Controller as the Agilent E1480A V/360. With this configuration, communication with the register-based amplifier module can be accomplished via four paths: 1. Embedded controller across the VXIbus backplane to the Agilent E1445A AFG (SCPI programming only). 2. Embedded controller to the Agilent E1405/06 Command Module via the GPIB interfa

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

to 50Ω or 75Ω, or to 0Ω for driving into high impedance. The output voltage can be attenuated by either 0 or 20 dB when 50Ω or 75Ω output impedance is selected. Output attenuation is unavailable with the 0Ω mode (high impedance). The main output terminal may be enabled or disabled under user control. When disabled, the output appears as an open circuit. This output is also overload protected via an output relay. The output relay automatically opens when an overload condition is detected
