7.3 Open-Loop Laboratory Test Fixture
In the open-loop laboratory test fixture (see Figure 7-6), high peak currents associated with loads necessitate careful grounding techniques. Timing and bypass capacitors should be connected close to the GND terminal in a single-point ground. The transistor and 5-kΩ potentiometer sample the oscillator waveform and apply an adjustable ramp to the ISENSE terminal.
