Interface connection and measurement
For connecting the EVK to a PC, use the included Micro-USB cable. Alternatively, a standard SUBD-9
cable can also be used. Additional measurement equipment can be connected to the front connector.

Active antenna
EVK-F9T evaluation kits include an ANN-MB1 multi-band (L1/L5) active GNSS antenna with a 3-
meter cable and SMA connector.
The recommended maximum antenna supply current for active antennas is 15 mA.

4.3.1
Antenna connector (RF IN)
An SMA female jack is available on the front side (see Figure 2) of the evaluation unit for connecting
an active GNSS antenna. A DC voltage of 3.3 V is provided to power the active antenna, and the RF
input is 3.3 V. The internal short circuit protection limits the maximum current to 60 mA. Note that
the 15-mA maximum supply current for the active antenna stays the same. This pin is also ESD
protected.
⚠
The connector is only to be used with a GNSS antenna or simulator. Do not connect this equipment
to cable distribution systems.
4.3.2
Timepulse connector (TP1)
The evaluation board includes a time pulse function providing clock pulses with a configurable pulse
period, pulse length and polarity (rising or falling edge). Check the ZED-F9T Data sheet [
] for detailed
specifications of configurable values.
