Greetings. I recently acquired two Z3805A gpsdo's from the usual auction site. (These units look like a Z3801.)
Does any one know the specified output level for the 1pps signals or have a high confidence measurement of the output voltage that they could share with me ? (Measuring fast rise time signals is not really my forte and I don't trust my measurements of an apparent .15 volt pulse.) The status message sent from the units via RS 232 contains a TFOM ( time figure of merit ?) variable and I've seen that phrase used in conjunction with equipment that outputs a 10 volt 1 pps pulse. On a side note so far I'm pleased with the performance of the units (the 10 Mhz output of better of the two has a typical adev in the low 10e-12 - high 10e-13 range, and appears to be improving.) Thanks in advance for any comments.
