20 to 100 kHz:
2 + 150
Impedance:
Up to 20 M ohm over available ranges
Connections
Test connections are made from the Controller's front panel Signal Out BNC connector to the test instrument.
Cables and connectors having minimal insertion loss over the bandwidth (DC to 300 kHz) are required.
Shut off the lower front-panel power/breaker switch to disable the amplifier module in the DSR 100-15 during this series of
tests.
No other peripheral connections will affect these tests.
Use common ground or isolated instruments, if possible. Select an environment with minimal radiated noise.
Temperature and run time:
Allow the DSR 100-15 Controller to run for 20 minutes in a quiescent state.
Settings and features not tested:
Sweep functions, Control functions, Duration setting
Output Assessment
The assessment of a waveform consists of setting up the DSR 100-15's user interface with the values as indicated for
each waveform type listed on the far left of Table 1. The duration may be set for several seconds, or more depending on
the triggering selected. The test varies voltage and, for alternating waveforms, a range of frequencies is given for each
voltage level.
Set up the test waveforms in the "User Defined Standards" Directory
Procedure for Phase Testing
A. Create a 0 VDC segment of short duration (no more than a few seconds)
B. Insert a trigger (True) after the 0 VDC segment
C. Insert a ripple waveform with the following settings:
D. Recommended Vp = 20 Vp (Start and End)
E. f = 1 kHz
F. Offset = 0 V
G. Sweep = LIN (ALL settings)
For testing each phase shift, enter the value of the phase for each test and start the waveform running. With the
oscilloscope trigger function set to capture the initiation of the ripple function, touch the space bar and measure the time
from the start of the (truncated ripple to the end of the first cycle. Repeat for each of the phase values shown in Table 1.
Assessment Table
Notes:
G = 20.0 for all waveforms
Use 0 VDC for offset setting for varying waveforms
