Description:
Information:
                                    The Model 849TA AC Power Controller is a frequency,
amplitude and phase controller designed to plug into all
California Instruments1 T Series AC power sources. The
frequency, amplitude and phase of the power source output
may be locally controlled using a keyboard on the front of
the controller, or remotely controlled through its IEEE-488
interface.
The controller output is a variable frequency, variable
amplitude, variable phase AC voltage. It provides the three-
phase input signal for the associated power source where it
is amplified to produce the high-power, multi-phase output.
Sense inputs for each of the three phases assures that the
voltage at the remote sense point equals the programmed
value. If the programmed voltage value cannot be maintained
within specified limits, the controller reduces the power
source output then displays an error message on its control
panel. The displayed message indicates which of the phases
has not been maintained at the programmed value.
Microprocessor-controlled, digital logic is employed in the
controller for frequency generation. Its sine wave outputs
are produced by a precision digital-to-analog converter.
Frequency accuracy is maintained by a quartz crystal whose
temperature stability is ±5 parts per million per degree
celsius.
The Model 849TA AC- Power Controller provides many features.
These features include:
- High-reliability CMOS design uses less than 2 watts of power.
- More than 20 programmable functions.
- Multi-page menu screen and 17 parameter screens for total
system programming and monitoring.
- Independent control of amplitude, phase angle, frequency,
voltage range and current limit on multi-phase systems.
Master/Slave configurations for applications requiring more
than 3 phases.
4 decades of frequency output with resolution to G.01 Hz.
Automatic frequency range changing.
Amplitude, frequency, phase angle and current limit may be
ramped incrementally via program control.Start, finish, step
size and step duration are independently programmable.
Sine or square wave output independently selectable on each
phase.
Programmable voltage ranges.
Simple IEEE-488 software using Abbreviated Plain English (APE).
Alphanumeric prompting display is user-friendly; no
reference codes are required.
3.2 character alphanumeric display.
2 0 key keypad for complete front panel control.
Complete programming (including IEEE-488 bus address and
calibration from the front panel) - no inside adjustments
are needed.
Non-volatile memory for instant set-up to pre-programmed
test parameters.
Non-volatile and volatile registers for storage of
programmable parameters.
System diagnostics with error messages on front panel display.
Internal clock tracks total elapsed time.
Internal counter tracks the frequency of an external signal
from 45 Hz to 450 Hz to provide a low distortion output.
