Unless you have a receiver that can be tuned to 433 MHz to hear the signal, about the only thing you can do is test communication between two 433 MHz transmit/receive modules.

I have never used the Holtek 12E digital code transmitter/receiver system. However, maybe you could measure the linearity by integrating the data output from its Data Select & Buffer using a simple R/C integrator and then watch the resulting integrated DC voltage change on a voltmeter as you step through A0 through A11 input codes.
