Notes

1

The digits of resolution in the above ratio measurements is set by the 

resolution parameter (

1.0E-6

, 

1.0E-9

). In effect, the exponent corresponds to 

the number of digits. See 

"Frequency Measurements"

 in 

Chapter 5

 for 

information on the relationship between gate time and reading resolution.

2

See 

Chapter 4

 for additional information on counter threshold levels and on 

configuring the input signal path.
