The test sheet on a typical (sample size of 1) E1938A test sheet states among other things Max slope near 0.T, 0 mHz/degree. (ie tempco < 1E-13/degree) So in practice, depending on what equipment is available, the measurement of the frequency change is likely to be extremely challenging. At best it may be possible to state that the frequency change is less than 1E-11 (substitute actual measurement resolution/accuracy limits). For an E1938A try bidding on one of the Australian sourced Z3815A's that keep popping up on ebay (however bids are relatively high).
