The Agilent Technologies 8904A Multifunction Synthesizer uses VLSIC technology to create complex signals from six fundamental waveforms. The standard 8904A digitally synthesizes precise sine, square, triangle, ramp, white noise, and dc waveforms and routes these signals to a single output.
Option 001 adds three more identical internal synthesizers (channels) which can either modulate the first synthesizer or be summed to the output. Frequency, amplitude, waveform, phase, and destination can be independently set for each synthesizer.
Available modulation types for channel A include AM, FM, F M, DSBSC, and pulse modulation.
Option 002 adds a second 50 Ω output, providing a second separate signal for two channel applications.
Option 003 adds fast hop and digital modulation capability to the 8904A. Option 005 allows multiple 8904As to be phase synchronized for applications which require the use of more than one 8904A.
Option 006 changes output one of the 8904A from a 50 Ω floating output to a 600 Ω, high-power bilance output. With this option, the 8904A can deliver 10 volts rms into a 600 Ω load from 30 Hz to over 100 kHz.
All this unique capability makes the Agilent 8904A a powerful new tool for demanding applications like VOR, ILS, FM stereo, and communications signaling.
