DESCRIPTION
The 8810A is a rack mount or bench top API featuring front panel controls (including touch screen display) and input terminals.
This self-calibrating unit is furnished with factory installed rubber feet and foldaway tilt stand and can also be installed in a
3.5” half rack slot. Using optional rack mounting brackets, the 8810A may be installed as a single unit in a full rack slot or as a
tandem mount of two units in a full rack slot.
This second-generation API truly represents a major step forward in Synchro-to-digital conversion technology. The use of an
intelligent DSP design eliminates push buttons and allows all programming to be done either via an integrated touch-screen, front
panel USB optical mouse interface or with the multi-purpose increment/setup knob. In addition, IEEE-488, Ethernet, and USB 2.0
interfaces have been added to extend remote operation capabilities. The display can be set for one of three display modes; 0-360º,
±180°, or Degrees, Minutes, Seconds. A wide frequency range (47 Hz to 20 KHz) is standard.
Improved flexibility is provided by two fully independent inputs that can be used to simultaneously read two separate input signals
or can be combined to measure multi-speed Synchro’s or Resolvers. The gear ratio, for the two-speed mode, is programmable from
2:1 to 255:1. Built-in phase correction eliminates errors caused by quadrature and harmonics when reference and signal are out of
phase by as much as 60°.
The 8810A automatically accepts and displays input voltages from 1.0VL-L to 90VL-L and reference voltages from 2Vrms to 15Vrms
over a broad frequency range of 47 Hz to 20 KHz. Therefore, one Instrument can handle most known Synchro and Resolver
measurement requirements.
The 8810A is a replacement for all variations of the previously supplied standard and special versions of the Model 8810. Contact
factory to determine compatibility.
Optional Reference: This design can also incorporate a 6 VA programmable reference generator that is used for standalone
applications (See P/N).

SAFETY SUMMARY
This symbol is intended to alert the presence of un-insulated dangerous voltage and shock hazard if
misuse or improper handling.
This symbol is intended to alert the presence of important information in the literature accompanying
this device. All information should be read carefully to avoid misuse and potential harm to the user
and/or device.
GENERAL SAFETY NOTICES
The following general safety notices supplement the specific warnings and cautions appearing elsewhere in the manual.
They are recommended precautions that must be understood and applied during operation and maintenance of the
instrument covered herein.
REPAIR
DO NOT ATTEMPT REPAIR. Under no circumstances should repair of energized instrument be attempted. All repairs
to this instrument must be accomplished at the Factory.
HIGH VOLTAGE
HIGH VOLTAGE is used in the operation of this equipment.
DEATH ON CONTACT may result if personnel fail to observe safety precautions. Learn the areas containing high
voltage on this equipment. Be careful not to contact high-voltage connections when installing, operating or maintaining
this instrument.
INPUT POWER ALWAYS ON
The design of the model 8810A is such that AC input power is continuously supplied to the power supply independent of
the front panel ON/OFF Switch. The primary means of disconnect is pulling the line cord from the instrument

A sample of the Factory Setting screen is shown below. Factory settings contain 10 sets of parameters that are
permanently configured at the factory. These parameters include the settings for reference source, reference voltage,
reference frequency and Synchro / Resolver configuration. The pre-set parameter is chosen by simply selecting the
button on the left, followed by the Load button. Once completed, the API will return to the main display screen and the
values are stored until changed. Settings 1 through 5 are shown below. Select “More>>” to see 6 through 10.
Figure 14 – Factory Setting
A sample of the Custom Settings Screen is shown below. The 8810A also contains the ability for the user to assign up
to 10 custom configurations. These parameters include the settings for reference source, reference voltage, reference
frequency and Synchro / Resolver configuration. Custom parameters are set by saving current parameters which have
been previously set up on the main screens and then saving them to the 10 custom settings. This is accomplished by
selecting the button to the left to choose the number 1 – 10 line and then selecting the Save Current button. The
previously saved parameter is then chosen by selecting the button on the left, followed by the Load button. Settings 1
through 5 are shown above. Select “More>>” to see 6 through 10.

A sample of the Brightness Control screen is shown below. Brightness of the display is adjusted from 0 to 100% by
touching the scale bar until the desired brightness percentage is obtained. Note that the brightness value is displayed
above the bar.

Shown below is the main Calibration Menu screen which contains a calibration routine for the Touchscreen display and
a calibration routine for the measurement circuitry of the 8810A.
The Touchscreen Calibration will give prompts for the user to touch the screen in two places. The Touchscreen
calibration calibrates the “user’s touch” calibrating the touchscreen input position with the displayed content. When
completed and successful, it will display “Calibration Complete”.
The Unit Calibration will start an internal circuit calibration which requires no user intervention or external equipment.
The unit will commence a full (off-line) calibration of all ranges (as opposed to background calibration which is
continually running and calibrates the unit seamlessly while the unit is on-line at the particular voltage/frequency the unit
is currently operating). Unit Calibration takes approximately 4 minutes to complete and will display “Calibration
Completed” after successful completion.
Figure 17 – Calibration Menu
Shown above are examples of the Help Menu screens. The help menu gives things such as specification summaries,
descriptions of available buttons and descriptions of available functions included with the 8810A. The Help Menu screen
shows the unit’s serial number, date code, MAC address, model information and firmware revision.

Default Values screen allow for restoring the 8810A to factory settings.
Figure 19 – Default Values
Each channel (0-360° or ±180° display mode only) can be independently set to provide a DC voltage representation of
either angular position (Vdc/degree) or angular velocity (Deg./Sec.). The D/A output range can be set to +/- 10 Vdc
max. See example below in Figure 20.
Figure 20 – D/A Setup
Two options are provided for setting the Bandwidth (BW) characteristics for each channel. As shown below, “Auto-
Bandwidth” or user preferred BW selection is possible as follows:
Auto-Bandwidth – The 8810A measures the reference frequency and then sets the BW to 12.5% of the ref. frequency.
The calculated BW will not exceed 100 Hz or be set below 6 Hz. This setting is the optimum for best compromise
between response / settling time and stability (Jitter of the lower LSB’s.) When this mode is selected the display
indicates the calculated BW setting in the BW Value window.
User Selected – The Auto-Bandwidth box unchecked allows the user to select the BW over the range of 6 to 1200 Hz.
It is recommended that BW not exceed 12.5% of the carrier frequency.

The 8810A includes a built-in strip chart feature which displays the angle readings in the form of a strip chart. Below is
a sample of the screen displayed
Figure 22 – Strip Chart Feature
The configure menu is shown in Figure 23. This menu allows the strip chart to be configured for the following
parameters:
•Data plotted as either angle, angle error or velocity
•Display of either channel 1, channel 2 or both channels
•Sampling rate (minimum 100 milliseconds, maximum 30 minutes)
•Upper and lower range
Figure 23 – Strip Chart Configuration Menu
The 8810A has a feature which allows Averaging of the Angle Readings. To access this feature select the angle
averaging button on the main display (shown below left). The averaging period may be set from 10 msec to 10 sec. The
number of angle readings which will be averaged is dependent on the rate of change of the angular data being
monitored. These values may be set by using the keypad or the knob shown above.
