MEASure:FREQuency:RATio? [{<expected>|MINimum|MAXimum| DEFault}
[,{<resolution>|MINimum|MAXimum|DEFault}]] [,<channel_pair>]

– expected is the expected ratio of the two input signals. resolution is the
desired resolution of the ratio measurement. The parameter ranges are:
expected (Option 106): 0.28 to 6.0E10 (default = 1.0)
expected (Option 115): 0.85 to 15.0E10 (default = 1.0)
resolution (all channels): 1.0E-15* expected to 1.0E-5* expected
(default
resolution corresponds to a 0.1s gate time)
–
channel_pair settings are (@1),(@2)|(@2),(@1). Within the pair, the first
channel represents the ratio’s numerator and the second channel represents
the ratio’s denominator. The default
channel_pair is (@1),(@2).
Frequency Ratio Examples
// using MEASure? - ratio measurement expecting a 1:1
// ratio, set 6 digits of resolution of ratio measurement
*RST // reset to start from known state
MEAS:FREQ:RAT? 1, 1.0E-6, (@1),(@2)
-----------------------------------------------------------------------
// using CONFigure - ratio measurement expecting a 1:1
// ratio, set 9 digits of ratio resolution
*RST // reset to start from known state
CONF:FREQ:RAT 1, 1.0E-9, (@1),(@2)
INP:LEV 1.5= // set a 1.5V threshold level (ch. 1)
