| Frequency Counter |
1 Hz to 9.999MHz, 1M ohm input impedance,
0.25 v rms to 50 v rms input |
| Square Wave Synthesizer |
1Hz to 1 MHz, 3 digit PLL accuracy, 5 volts,
or 12 volts digital output |
| Speech Synthesizer |
The 68HC11 uses a speech synthesizer chip
(instead of a display) for verbal output |
| Sine Wave Generator |
1Hz to 100 KHz, 0.02% distortion, 10, 1, or
0.1 volts peak-to-peak output with 3 digit PLL
accuracy |
| EEPROM Programmer |
Changes to the 68HC11 EEPROM can be
programmed directly from the keypad on this
instrument without a terminal or computer. Minor
software patches can therefore be done directly
from the keypad. |
| Programmable Filter |
The 68HC11 controls an analog state variable
active filter that can be set for lowpass,
bandpass, or highpass (2-pole) function with the
cutoff frequency controlled by the 68HC11 from 1
Hz to 100 KHz. Shifts in the analog components
due to temperature are automatically compensated
for by the 68HC11. |
| Capacitance Testor |
The 68HC11 controls circuitry that will
measure capacitance from 1 pf to 0.1 uf with 1 pf
resolution. |
| Inductance Testor |
The 68HC11 controls circuitry that will
measure inductance from 1 microhenry to 0.1
Henries with 1 microhenry accuracy. |
