I'm wondering if it's possible to use two tinySA's (in signal-generator mode) to make tests of a receiver's dynamic range. In ARRL reviews of various radios, two signals are injected 2 kHz apart with the idea being to note the receiver's response to one signal while the other signal's level is increased. Rather than a sig-gen with two outputs (that the ARRL lab probably has) could two tinySA's be used? I'm thinking they could if they could be isolated from influencing each other, so something more than a T-connector would be needed to combine them into a single input to the receiver.
Has anyone done this or able to suggest a way to combine the two outputs from the sig-gen together?
