Rounding Numeric Entries; Settling Times - Fluke 5700A Series II Operator's Manual

The voltage range boundaries in the 5700A/5720A Series II are different than those
in the 5200A; therefore any discontinuities that can occur at voltage range boundaries
will now appear at a different voltage. If you compensate for these discontinuities in
your programs, you may wish to determine the new boundaries so that you can
modify your programs accordingly.
Some examples of the difference in the voltage ranges are as follows: The 5200A
sources 11.99999V in the 10V range, and 12V in the 100V range; the 5700A/5720A
Series II sources 21.99999V in the 22V range, and 22V in the 220V range.

Frequency Limits
Unlike the 5200A, the 5700A/5720A Series II cannot source frequencies between
1.1000 MHz and 1.1999 MHz. Instead, the 5700A/5720A Series II generates an out-
of-range-error for all frequencies above 1.1000 MHz.
•
Programming Values Outside the Volt-Hertz Capability
If you program a voltage or frequency that is outside the volt-hertz capability of the
5700A/5720A Series II, you will receive an out-of-range error. This is a change from
the 5200A, which remains in operating mode and compensates for out-of-range
values by maintaining the existing frequency, and reducing the voltage to the
maximum the calibrator can source.
A graph displaying the volt-hertz capability is provided in the Specifications for AC
Voltage. Refer to Chapter 1 for the 99%-level specifications, and to Appendix D for
the 95%-level specifications.

5-67. Rounding Numeric Entries

When a number is entered that is longer than the resolution of the 5700A/5720A Series
II, the entry is rounded to the next highest value, whereas the 5200A truncates the entry.
For example, the entry 119.999999V is rounded to 120.0000V in the 5700A/5720A
Series II, but is truncated to 119.9999V in the 5200A.

5-68. Settling Times

The 5700A/5720A Series II and the 5200A have different settling times. The
5700A/5720A Series II uses the SETTLING bit for all programming commands; the
5200A used the SETTLING bit only for voltage and frequency commands. After a GPIB
command has been received, the 5700A/5720A Series II can take up to 60 ms to set the
SETTLING bit.
To determine if the 5700A/5720A Series II has settled, check the SETTLING bit in either
the serial poll status byte, or in the status message.
