4.9-6 Section 4: Using the Model 9100: Frequency Function
Final Width = 215mm
4.9.5.1 Frequency Resolution Thresholds
The different frequency resolutions are distinguished by two characteristics:
• Lowest and highest frequencies available.
• Absolute resolution of the least-significant digit.
The following table shows the spans of output frequencies for the Frequency function,
against their associated resolutions and output voltage limits.
4.9.5 Crossing Thresholds
Increasing Frequency
Using the
key in Digit Edit facility; an audible warning will be given if the new value
is too large for the present span of frequencies, with a reminder ('
Up range required ') on
the screen. The user must change to the next lower resolution, with a larger span of
frequencies, using the
key. This rule applies whether OUTPUT is OFF or ON.
When using either the X10 screen key or the Direct Edit facility; if the new frequency is
too large for the present resolution, a lower resolution will be activated with a larger span
of frequencies. No warning will be given. This rule applies whether OUTPUT is OFF
or ON.
Decreasing Frequency
Using Digit Edit; frequencies down to 100Hz lie within all spans, but to select frequencies
below this, one of the three lower spans of frequency must be used.
If the required frequency lies between steps of the present resolution, then the user must
increase resolution using the
key, also reducing the span of frequencies. This rule
applies whether OUTPUT is OFF or ON.
Using either the ÷10 screen key or Direct Editing; if the required frequency lies between
increments of the present resolution, a greater resolution will be activated with reduced
span. No warning will be given. This rule applies whether OUTPUT is OFF or ON.
