6.5 Dividing the Output
Procedure
1.
Turn the m dial.
The m display shows the denominator of the divider value (the number of divisions).
2.
Turn the n dial.
The n display shows the numerator of the divider value.
Divider value example: x —
1
5
1. Set denominator m.
2. Set numerator n.
Explanation
The 2558A outputs voltage or current by dividing the frequency specified in section 6.2.
The voltage and current levels are not divided.
The range for denominator m is 4 to 15.
The range for numerator n is 0 to m.
Turning the m dial resets numerator n to the denominator m value.
The n value cannot be set larger than the m value.
When the power is turned on, denominator m that was used previously is restored. The numerator n is
reset to the denominator m value.
For example, if FREQUENCY METER MIN is set to 45 Hz and MAX is set to 65 Hz and you set the
denominator m to 4, the following division occurs.
65 Hz – 45 Hz = 20 Hz
The output is divided at 5 Hz intervals (1/4 of 20 Hz).
n/m = 0/4 : 45Hz
n/m = 1/4 : 50Hz
n/m = 2/4 : 55Hz
n/m = 3/4 : 60Hz
n/m = 4/4 : 65Hz
