6.1 System Functionality
ZPX-A is a Mode S, Level 2els, Class 1 transponder with support for ADS-
B extended squitter, elementary surveillance, and SI code. A control that
provides for enabling X-bit for Mode 3/A replies is provided. The nominal
conducted power output is about 54 dBm, meaning AIMS 17-1000 App. G,
§3.1 transmit power of 52 dBm (158 W) is met when the antenna cable has
< 2 dB attenuation. ADS-B OUT meets DO-260B Class B1S.
This transponder replies to both legacy Modes A and C interrogations and
to Mode S interrogations from both ground radar and airborne collision
avoidance systems. In all cases, the interrogations are received by the
transponder on 1030 MHz, and replies are transmitted on 1090 MHz.
