https://www.omicron-lab.com/products/vector-network-analysis/accessories/b-amp-12-amplifierI'm looking for something like the Omicron Lab B-AMP 12 Power Amplifier, but less expensive and with reduced specs. I only need 1 Hz to 20 MHz, while the B-AMP 12 is DC to 50 MHz. Also voltage can be lower, and the gain can roll off in the higher frequencies.
Basically what I want to do is amplify my AWG, and then script the AWG and oscilloscope to make a frequency-response analyzer. It's for hobby use, otherwise I'd shell out for a real FRA.
I've searched quite a bit, but it seems pretty difficult to search with Google or on the various marketplaces. I keep finding either audio amps without high frequency, or RF amps without low frequency. Browsing test equipment sites hasn't turned up anything comparable, either. The closest I've seen is a demo board for a variable gain amplifier, but the specs were too low.
Does anyone know of a similar alternative?
Or how to find something like this? Thanks in advance.
