connected to a higher voltage, through a high-side load. A
TTL high signal applied to CS enables a 10kHz oscillator,
which quickly develops 15V at the gate of the MOSFET,
clamped by a zener diode. A resistor from the gate to ground
ensures that the FET will turn off quickly when the MIC1557
is turned off.

If an additional charge or discharge source is connected to
the timing capacitor, the frequency may be shifted by turning
the source on or off. An MIC1555 oscillator, powered by the
circuit under test, may be used to drive a small loudspeaker
or piezo-electric transducer to provide a medium frequency
for an open or high impedance state at the probe. A high tone
is generated for a high level, and a lower frequency for a logic
low on the probe.
