The easiest way to test a pulse transformer is using your oscope. The people with a Fluke scope that has three different cal tests is probably the best one to play with. Others will have the 1 or 5 volts cal that can be used. But all work equally as well as the other. I just like playing with more then one.
Right now I am testing using a 1 vpp signal @ 1khz. You have to remove one of the terminals on the primary side to open the circuit. Apply your signal there and put the scope on the secondary. If you have amplification the transformer is good, if its flat or lower then the signal applied its bad. To get an idea of what a bad one looks like, put the cal on the secondary side and the scope on primary and you will get a idea what a bad one will look like. Also remember that you must disconnect the secondary if you wish to try that.
vpp input .488 output 2.28
acv input .172 output .808
freq input 5khz output 13.1khz
db input 13 dbm output .3 dbm
I am using the scope on the primary and secondary. Notice the change in frequency from the 1khz being applied and then changing to 5khz on the input.
