• Frequency counter: it must be precise to be able to measure 1Hz (precision; ± 4ppm).
Hewlett Packard, 53131A is recommended.
• DC power: it must be able to output at least 1A current under 2.4V for Handset.
• Digital multi-meter (DMM): it must be able to measure voltage and current.
• Oscilloscope
