8. Check that this frequency is greater than 50 MHz, and record the
frequency on the test record.
B. Check DC Accuracy
1. Set the DC Power Supply output voltage to approximately 0 V.
2. Remove the AP015 from the oscilloscope, and reconnect using the
ProBus extension cable. Install a BNC T connector, BNC cable, and BNC
to dual banana plug adapter as shown in the figure on the following
page. Connect the dual banana plug adapter into one of the digital
multimeters.
3. Using banana patch cords, connect the 'V Source' terminal of the 50
Turn Calibration Loop, AP015-CF01, to the positive output of the power
supply. Connect the 'V Return' terminal to the power supply negative
terminal. (Refer to Figure 1, DC Accuracy Test Set Up.)
4. Connect the Current Sense terminals of the 50 Turn Calibration Loop to
the voltage inputs of the second digital multimeter.
