SparkFun TRRS 3.5mm Jack Breakout
TRRS connectors are the audio-style connectors that you see on some phones, MP3 players and development boards. TRRS stands for "Tip, Ring, Ring, Sleeve," which reflects the fact that, unlike a standard stereo connector, this actually has three conductors and a ground. Some devices use the extra conductor for a microphone (like hands-free headsets) or to carry a video signal (like in some MP3/MP4 players). This breakout board makes it easy to add a TRRS jack to your prototype or project by breaking out each conductor to a standard 0.1" spaced header.

High Voltage Probe: Single-Ended
A high voltage single-ended probe is typically used for measuring ground referenced signals up to 40 kV. However, some single-ended probes are designed for oscilloscopes with isolated or floating inputs for measurements that are not ground referenced. Users should select probes with a low input capacitance specification (< 4 pF) to minimize the probe’s loading effect on the circuit because a probe with lower input capacitance will offer higher input impedance at higher frequencies.

Active Monopole Antenna
AM-741
The 41 inch Monopole antenna is required for making electric field emission measurements below 60 MHz per Military standards (MIL-STD-461) and FAA (DO-160) specifications. This antenna is for emissions measurements only. It cannot be used for transmitting. The Active Monopole antenna is generally used in a shielded room or in a screen room, with the equipment under test (EUT) placed on a metal ground plane. The 41 inch rod and the ground plane behave electrically as though a mirror image of the rod were located below the ground, and the ground removed. Since the stainless steel plate does not have enough surface area to mirror the entire 41 inch rod, it is bonded to the surrounding ground plane during use. The AM-741 is battery powered to prevent measurement errors that maybe caused by external power cables. The ANSI equivalent capacitance substitution (ECSM) method is the recommended method for calibrating AM-741 monopole antenna. The individual calibration data will be included with each antenna.
