DESCRIPTION
This single slot VXI (“C”-size card) is an Instrument/Embedded Grade, intelligent DSP design, that incorporates
up to four Synchro/Resolver Measurement channels, and up to four Instrument Grade Synchro/Resolver
Simulation channels or up to eight Embedded Grade Synchro/Resolver (Simulation) channels that can be used
independently and/or simultaneously. The internal modular design of the card utilizes a motherboard that may be
populated with up to two daughter cards. Each daughter card, instrument grade or embedded grade, may each be
populated with S/D, D/S or REF modules, depending on the grade type (see configurations following).
Instrument Grade is defined as 0.005° Accuracy
Embedded Grade is defined as 0.015° Accuracy (less accurate than Instrument Grade but offers a higher
channel density.
Two Reference Supplies are available (one on each daughter card). If > 2 Reference supplies are required, the
additional Reference(s) will replace Stimulus channels (contact factory for special configurations).
All measurement and simulation channels are user programmable for either Synchro or Resolver format and may
be formatted for either single-speed or multi-speed applications. Programmable speed ratios (2:1 to 255:1) offer
additional flexibility for those applications requiring two-speed capability.
Each Simulation channel can be programmed for either continuous rotation or programmable Start and Stop
angles.
This instrument contains all the necessary functions to fully evaluate, calibrate and simulate the Synchro/Resolver
components and systems. With its built-in reference generators, superb accuracy, resolution and high power
output capability, this module can form the basis of a fully integrated system for testing any Synchro/Resolver
signal. This design also incorporates our new internal wrap-around Self Test capability that does not require any
external hardware.
21st Century technology combined with nearly 50 years of synchro/resolver product experience yield state-of-the-
art performance and accuracy.

GENERAL ARCHITECTURE
This universal card eliminates the need for specialized simulation and measurement for Synchro/Resolver
components and systems. The card architecture consists of a motherboard with two daughter-boards that enable
the user to specify a variety of functions within this single slot card design. (See part number for details).
The daughter-boards consist of independent measurement / stimulus / reference modules that may be populated
to provide up to four Synchro/Resolver Measurement channels and up to four Instrument Grade
Synchro/Resolver Simulation channels or up to eight Embedded Grade Synchro/Resolver (Simulation) channels
that can be used independently and/or simultaneously.
Fig 1. Instrument / Embedded Board Daughter Card Combination
– Typical configuration example: (Note) – One or two Daughter Boards can be mixed / matched (at factory /
time of order) to suit configuration preference.
– If a second and/or third reference supply is specified on an Instrument Grade daughter card, it replaces
D/S channel 2 then 1 respectively and only RHi and RLo (S1, S3) pins are active. (Please contact factory
for special configuration requests).

PROGRAMMING
The 65CS4 can be supplied with either Native (See below) or Mate/CIIL Syntax (See page 18). See P/N for
specifying the required format.
Native Syntax
One VXI 65CS4 supports up to 4 channels of measurement and stimulus (see configuration in part number). Use
SW1 to configure the address for those channels. (SW2 is not used). Use Native Syntax to address any channel
of that associated logical address.
Self-test can be performed at any time without effecting any set parameters. Self-test requires approximately 45
seconds to complete.
TO POWER ON CARD AND ENABLE OPERATION, user must initially send the command: *IDN?
Perform self-test (*TST?<CR><LF>) before programming. Testing is complete in approximately 45 seconds.
The following sections define Native programming format with supporting examples
Software / Driver Support
The VXI Software Support Kit (SSK) is supplied with all VXI platform based board level products. This platform’s
SSK contents include “help” documentation which defines the command set. An IVI driver is provided for each
card function implementation. A sample LabWindows application is provided for simple instrumentation, card test
and debug.

SD BANDWIDTH = HIGH
SD DC SCALE = 1000
SD RATIO = 1
SD REF SOURCE = EXT
SD STATE = OPEN
SD UPDATE = TRACK
REF FREQ = 400

Note *1 – SIMULATOR TRIGGER CONTROL DEFINIITIONS
The BUS, INT, EXT and TTL triggers relate to the Rotation Command only;
Each DS (stimulus) channel has an independent Trigger Source (and associated Trigger Slope) – there are four
sources available;
If the TRIG_SOURCE is set to <INT>; (which is default); the DS will rotate upon execution of the ROT_INIT
command.
If the TRIG_SOURCE is set to <BUS>; the DS will rotate upon execution of a low level command EDFF(h)
If the TRIG_SOURCE is set to <TTL>; the DS will initiate rotate upon TTL signal application on the VXI chassis
backplane I/O P2 connector. You can set the individual channel to trigger on one of 8 possible signal inputs. This
is identified as:
P2-23A TrigTTL0
P2-24A TrigTTL2
P2-26A TrigTTL4
P2-27A TrigTTL6
P2-23C TrigTTL1
P2-24C TrigTTL3
P2-26C TrigTTL5
P2-27C TrigTTL7
If the TRIG_SOURCE is set to <EXT>; the DS will initiate rotation upon application of the trigger signal from the
front panel connector.

VLL_VOLT? Line-to-Line input/output voltage value
RATIO? Speed Ratio value
REF_VOLT_IN? Input Reference Voltage Setting
ROT_DONE? Step Rotation Status
ROT_RATE? Rotation Rate
ROT_STOP_ANGLE? Stop Angle
REF_SOURCE? Reference Internal (INT) or External (EXT)
TRIG_SOURCE? Trigger Source
TRIG_SLOPE? Trigger Slope
BANDWIDTH? Returns Bandwidth
MAXT? API stable measurement timeout value
STATE? Relay State OPENED or CLOSED
UPDATE? Generator velocity value
VEL? Velocity
*TST? Self test status. Self-test requires approximately 45 seconds to complete.
*IDN? Instrument Identification string.
Initially required to power on card and enables operation.
*ERR? Returns 10 recent error messages
