System Calibration
IMPORTANT: Before operating the DSR 100-15, the Calibration Test should be run to determine the correct system
settings for the DSR 100-15.
The DSR 100-15's default System Gain setting is 20, and the default DC Offset setting is 0, but these settings should be
verified and adjusted, if needed, to reflect the measured gain of your DSR 100-15 system at the Test Supply outputs. If
you are measuring the output of the DSR 100-15 without amplification (from the Controller's front-panel BNC signal
output), a System Gain of 1 can be used for DSR 100-15 calibration (for an expected output of
10Vp/20Vpp).
Complete the following steps to run the calibration test and adjust the DSR 100-15's System Gain and DC Offset settings:
1. Select the Settings button and then open the System Calibration tab.
2. Make sure an estimated gain is entered in the Amplifier Gain input box. A default gain of 20 will be pre-entered in
this box.
3. Adjust the Calibration Test Voltage, if desired. A default test signal of 1 Vp will be pre-entered in this box. Note: the
default DC offset is 0 and cannot be changed.

4. Connect an oscilloscope to the DUT (load at the Test Supply output).
5. Press the Run Calibration Test button to begin the Calibration Test. The DSR 100-15 will generate a 1 kHz sine
wave signal at the test voltage entered in the Calibration Test Voltage box.

6. Note the output voltage and any DC offset shown on the oscilloscope. Enter these results in the Measured Output
and Measured DC Offset boxes on the System Calibration tab. The DSR 100-15 Controller will automatically
calculated the required Gain and DC Offset adjustments and display them on the Applied Gain Ajustment and
Applied DC Offset lines on the System Calibration tab.

7. Press the Save button to save the resulting calibration numbers and close the Settings window.

Basic Operation
IMPORTANT: Before operating the DSR 100-15 system, the System Calibration Procedures should be performed to
determine the correct System Gain and DC Offset settings for the DSR 100-15. See the "System Calibration" topic for
more information.
1. Select the Settings button and then open the System Calibration tab to set the DSR 100-15 system gain. The
default setting for a DSR 100-15 system is 20, but this should be calibrated to match your actual system gain. If
measuring DSR 100-15 Controller output directly (without amplification), the system gain can be set to 1 for a
10Vp/20Vpp output.
2. Use the Files button to load a test from the Standards library.

3. Use the Add Wave and Add Control buttons to select a waveform or control to add to the active test window.
4. Select the tab for a waveform or control to open the Properties dialog. Edit the properties to create complex
waveforms and waveform sequences.

5. Segments can be dragged to change their order. To remove a segment from the test, press the X on the segment's
tab.

6. When your test sequence is complete, press the Arrow button to begin generating signal output from the amplifier.

Adding Waveforms
The Add Wave button opens a drop down menu listing the types of waveforms that can be added to the active window.
You can choose Sine, Ripple, DC, Triangle, Square or Sawtooth waveforms.
When you choose a waveform from the Add Wave drop-down menu, the default waveform of that type is added to the
active window. Click on the tab or the waveform in the display to open the Properties form containing the available
property settings for that waveform. See the individual entries in this Help system for more information about the settings
available for each waveform type.
As you add or adjust settings for the waveform in the Properties tab, the visual depiction in the active test window will
adjust to reflect the approximate signal being described by the waveform properties. Note that time sequences are NOT to
scale.
To add additional waveforms to the active test, select additional waveforms from the drop-down menu. New waveforms
will be added sequentially and will appear to the right of the selected control or waveform in the active window.

Position Waveforms: To reposition a waveform within the test sequence, click on the waveform to highlight and then
click and drag the waveform to the desired position in the sequence.
Enable/Disable Segment: Each waveform segment can be set to Enabled (Segment Enabled checkbox checked) or
Disabled (unchecked). When enabled, the waveform will be played as part of the test sequence. When unchecked, the
waveform will be skipped during the running of the test segment. This can be useful when building or troubleshooting test
sequences to skip over long or previously verified segments.
Segment Calibration: Each waveform segment can be individually calibrated using the segment calibration procedure.
This can allow minor adjustments in system gain to be performed for a single segment.
To perform segment level calibration, complete the following:
1. Locate the segment to be calibrated and press the blue Calibration button located to the right of the waveform
properties. The Segment Calibration window will open.
2. Connect an oscilloscope to the DUT (load at the amplifier output).
3. Press the Run Calibration Test button to begin the Calibration Test. The DSR 100-15 will continuously generate a
waveform with the amplitude and frequency defined in the wave properties.
4. Note the output voltage shown on the oscilloscope. If the output does not match the test voltage, enter the amount
required to adjust the output to match the test voltage in the Wave Gain input box. For example, if the oscilloscope
reading is 1.1 Vp, enter -0.1 in the Wave Gain input box. Rerun the Calibration Test to verify the calibration, and
then press the Close button to save your adjustment and close the Segment Calibration dialog.
NOTE:The calibration test can only produce voltage levels within the voltage limits of the system. If levels above system
limits are entered in the Wave Gain input box, the calibration test levels will remain at the highest level capable.

Adding Controls
The Add Control button opens a drop down menu listing the types of controls that can be added to the active window. You
can choose Trigger, Fixed Loop, Variable Loop, Template, or GPIO Output.
When you choose a control from the Add Control drop-down menu, an icon representing that control type is added to the
active window, and a form containing the available settings for that control opens below the active test display. See the
individual entries in this Help system for more information about the settings available for each control type.
To add additional controls to the active test, select additional controls from the drop-down menu. New controls will be
added sequentially and will appear to the right of the selected waveform or control in the active window. To reposition a
control within the test sequence, click on the control to highlight and then click and drag the control to the desired position
in the sequence.

Running a Test
One or more waveforms and/or controls that have been added to the active test window can be run using the controls located
below the active window.
RUN: When the Run button is pressed, the active test sequence will be sent to the DSR 100-15, and the system will
begin generating signal starting at the beginning of the test sequence (the waveform or control farthest to the left). The
System Status reporting message will change from 'Idle' to '1 of X,' with X being the total combined number of waveforms
and controls in the test.
An individual segment may be highlighted in the active test window during playback. This occurs when the DSR 100-15
system is currently generating the highlighted segment and the segment is equal to or greater than one second in duration.
Segments shorter than one second are too short to register as being highlighted.
STOP: When the Stop button is pressed, the DSR 100-15 will stop signal generation, and the test will reset to the start of
the first waveform. The system will report its status as 'Idle.' The system will also report its status as Idle at all times that the
DSR 100-15 is operating normally but a test is not active .
OUTPUT ENABLED/DISABLED: When the Output Enabled button is displayed, the signal defined by the
active test sequence will be generated by the DSR 100-15. When pressed, the Output Enabled button will toggle to the
Output Disabled display , and the test sequence can be run without generating output signal. This can be

useful for testing a sequence before generating output.
