pg. ii_DaqCal 918494 User Calibration Guide, 457-0931 rev 1.0 Equipment Refer to the appropriate block below , depending on whether you w ill be calibrating through a 37-pin, 68-pin, or 100-pin connector . P1 37-PIN If calibration signals w ill be passing th rough a 37-pin P1 connector you w ill need : Required : 6.
NIST T raceability Calibration test equipment should be traceable through the National Institu te of Standard s and Technology. (NIST). Customers not familiar with traceability through that institute should contact them at traceability@nist.gov The NIST Policy on Traceability (contained in NIST Administrative Manual, Subchapter 5.
P1 (37-pin) For DB37 P1 applications you can at tach a DBK11A to the device via a CA-37 cable. Connecting a DBK11A P4 (100-pin) For 100-pin P4 connector applications you can use a DB K200 (or DBK201), DBK11A, and a CA-195 cable; or you could use a DB K213 and a CA-195 cable.
After you have completed the setup according to the type of device and appropr iate connectivity option, launch DaqCal and follow the on-screen i nstructions. What to Expect when using DaqCal When DaqCal open s you will be prompted to select your device from a list.
From the screen’s Cal ibration List (right-hand figure), select the desired types of cal ibration. In the example shown we have selected: o Channel Offset A/D (Single-Ended) o Channel Gain A/D (Single-Ended) After making the selections, click the <Calibrate> button (see preceding figure).
Calibrating Analog Outputs After launching DaqCal, sel ect the device to be calibrated from the device invent ory list. After selecting your device, click th e <OK> b utton. An instruction screen with a Calibration List will display. From the screen’s Calibrat ion List select the desired types of calibration.
Calibrating DBK Expansion Options If the primary data acquisition device (DaqBook, or DaqB oard) is out of its calibration period, calibrate that device prior to calibrating the DB K expansion option. An alternative to using DaqCal is to contact the factory or your service representative to schedule a factory calibration.
Counter Input Modes 5 Debounce Module …… 5-1 Terms Applicable to Counter Mode s…….5-5 Counter Options …… 5-5 Counter/Totalize Mode …… 5-6 Period Mode …… 5-8 Pulsewidth Mode …… .
Trigger After Stable Mode In the “Trigger After Stable” mode , the output of the debounce m odule w ill not change state until a period of stability has been achieved. This means that the input has an edge a nd then must be stable for a period of time equal t o the debounce time.
T2 – During time period T2, t he input signal is not stable for a length of t ime equal to T1 (the debounce time sett ing for this example.) Therefore, the output stays “hi gh” and does not change state during time peri od T2.
Use trigger before stable mode when the input signal has groups of glitches and each group is to be counted as one. The trigger before stable mode will recognize and count the first glitch within a group but reject the subsequent glitches within the group if the debounce time is set accordingly.
DaqBoard/3000 Series User’s Manual 918494 Counter Input Modes 5-5 Terms Applicable to Counter Modes The following term s and definitions are provided as an aid to understanding count er modes. Gating: Any counter can be gated by t h e mapped channel.
Encoder Mode (see page 15). OPT[1:0] : Determ ines the encoder measurement mode: 1X, 2X, or 4X. OPT2 : Determines whet her the counter is 16-bits (Counter Low); or 32-bits (C ounter High). OPT3 : Determines whic h signal latches the counter outputs into the data stream going back to the /3000 Series board.
An explanation of the various counter opt ions, depicted in the previous figure, follows. COUNTER: OPT0: This selects totalize or clear on read mode. Totalize Mode – The counter counts up and rolls over on the 16-bit (Low Counter) boundary, or on the 32-bit (High Counter) boundary .
Period Mode TIP: When using a counter for a trigger source , it is a good idea to use a pre-trigger with a value of at least 1. The reason is that all counters start at zero with the in itial scan; and there will be no valid reference in regard to rising or falling edge.
DaqBoard/3000 Series User’s Manual 918494 Counter Input Modes 5-9 PERIOD: OPT[1:0]: Determines the number of periods to time, per measurement . This makes it possible to average out jitter in the input waveform, sam pling error, noise, etc.
5-10 Counter Input Modes 918494 DaqBoard/3000 Series User’s Manual Upper 16-bits of the 32-bit counter Lower 16-bits of the 32-bit counter Range (Hz) Ticksize (nS) Averaging Option Range (Hz) Ticksize (nS) Averaging Option 15u – 1500u 20833.333 1 1 – 100 20833.
Pulsewidth Mode TIP: When using a counter for a trigger source , it is a good idea to use a pre-trigger with a value of at least 1. The reason is that all counters start at zero with the in itial scan; and there will be no valid reference in regard to rising or falling edge.
5-12 Counter Input Modes 918494 DaqBoard/3000 Series User’s Manual PULSEWIDTH: OPT2: Determines whether t h e pulsewidth is to be measured with a 16-bit (Count er Low), or 32-bit (counter High) counter.
Timing Mode TIP: When using a counter for a trigger source , it is a good idea to use a pre-trigger with a value of at least 1. The reason is that all counters start at zero with the in itial scan; and there will be no valid reference in regard to rising or falling edge.
An Example of Timing Mode The following exampl e represents one channel in timing mode. The t ime desired is between the rising edge on the input channel and the fall ing edge on the mapped channel . Zeroes are returned, in the scan, until one complete time measurement has been taken.
Encoder Mode TIP: When using a counter for a trigger source , it is a good idea to use a pre-trigger with a value of at least 1. The reason is that all counters start at zero with the in itial scan; and there will be no valid reference in regard to rising or falling edge.
Representation of Quadrature Encoder Output s: A, B, and Z As the encoder rotates, the A (or B) sign al is in di cative of the distance the en coder has traveled.
ENCODER: OPT[1:0]: This determi nes the encoder measurement mode: 1X, 2X, or 4X. ENCODER: OPT3: This determi nes which signal latches the counter outputs into the dat a stream going back to the /3000 Series board. Normal ly, the start of scan signal latches the counter output s at the beginning of every scan.
Wiring for 1 Encoder The following figure illustrates connections for one encoder to a 68-pin SCSI connector on a DaqBoard/3000 Series board. The “A” signal must be connected to an even-numbered channel and the associated “B” signal must be connected to the next [h igher] odd-numbered channel.
A typical acquisition might ta ke 6 readings off of the 3000 Series boa rd module as illustrated below. The user determines the scan rat e and the number of scans to take. DaqBoard/3000 Series board Acquisitio n of Six Readings per Scan Note : Digital channels do not take up analog channel scan time.
Wiring for 2 Encoders The following figure illustrates single- ended connections for two encoders . Differential connections are not applicable. Two Encoders Connected to pins on the SCSI C o nnector* * Connections can instead, be m ade to the associated screw-terminals of a connected TB-100 terminal connector option.
Setpoint Configuration for Output Control 6 Overview …… 6-1 Detecting Input Values …… 6 -3 Controlling Analog, Digital, and Timer Outputs …… 6-4 P2C, DAC, or Timer Update Latency …… 6-.
DaqBoard/3000 Series boards include a setpoi nt configur ation feature which allows the user to indi vidually configure up to 16 detection setpoi nts associated with channels within a scan group.
Detecting Input V alues All setpoints are program med as part of the pre-acquisition setup, si milar to setting up the analog pat h , debounce mode, or counter mode setup. Since each setpoint acts on 16-bit data, each has two 16-bit compare values: Limit A (High Lim it) and Limit B (Low Limit).
Controlling Analog, Digital, and T imer Outputs Each setpoint can be program med with an 8-bit digita l output byte and corresponding 8-bit m ask byte. When the setpoint criteria has been m et, the P2C digital output port can be updated with the given byte and mask.
The setting of a detection wi ndow must be done with a scan period in mind. Thi s applies to analog inputs and counter inputs. Quickly changing analog input voltages can step over a setpoint wi ndow if not sampled ofte n enough.
P2C, DAC, or T imer Update Latency Setpoints allow DACs, t imers, or P2C digital output s to be updated very quickly. Exactly how fast an output can be updated is dete rmined by the following three factors: o scan rate o synchronous sampling mode o type of output to be updated Example : We set an acquisition to have a scan rate of 100 kHz.
More Examples of Control Outputs Detection on an Analog Input, DAC and P2C Updates Update Mode: Update on True and Fal se Criteria: Ch 5 example: Below Lim it; Ch 4 example: Inside Window In this exam.
In the example [upper portion of the preceding figur e], the setpoint placed on analog Channel 5 updated DAC1 with 0.0V. The update occurred when Channel 5’s i nput was less than the setpoint (Limi t A). When the value of Channel 5’s input was above setpoint Limit A, the condition of <A was false and DAC1 was then updated with minus 1.
Using the Hysterisis Function Update Mode: N/A, the Hysterisis option has a forced update built into the function Criteria Used: wi ndow criteria for above and below the set limits The figure below shows analog input Channel 3 with a setpoint which defines two 16-bit li mits, Limit A (High) and Limit B (Low).
Using Multiple Inputs to Control One DAC Output Update Mode: Rising Edge, for each of 2 channels Criteria Used: Inside Window, for each of 2 channels The figure below shows how multiple inputs can update one output. In the following figure the DAC2 analog output is being updat ed.
