TDS 7054 query max and min measurement

[JakeKing]

I seem to be having difficulty querying for the maximum and minimum measurements on my TDS 7054 o'scope. I have both meaurements on and if I query MEASU:MEAS1:TYP? it returns MAX and returns MIN for MEAS2. yet when i try to query the actual value MEASU:MEAS1:MAX? it returns 99.000+36 which of course cannot be true. The strangest part is that the code works for the DPO4104. Any Idea what I'm doing wrong? I've attached 2 sets of code, 1 is how I turn the measurements on on the scope, the other is trying to query for max and min.

You should be using ":MEASU:MEAS%d:DAT?" to get your data (put the number in for the %d).  You are actually requesting the maximium max value the scope has recorded.  It can keep some statistics on measurements.  Here are the commands I use to get the data (again, replace %d with the measurement number):

:MEASU:MEAS%d:DAT?
:MEASU:MEAS%d:UNI?

 The first command requests the actual data of the measurement and the second requests the units of the measurement.

thank you for your quick reply

DAT is not an acceptable command on these scopes, but if i use VALue instead it works like you said it should.

Thanks again.

"MIN" is not acceptable for your scope, you must use "MINI"

MIN works fine thank you though
