B Rear-panel connectors

The following sections describe the connectors on the rear-panel of the PolaRx5.

B.1 MAIN (TNC)

Connect an active GNSS antenna to this connector. The gain at the connector (antenna gain
minus cable losses) must be in the range 15 to 50dB.

By default, the receiver provides a 5V DC supply on the MA

I

N connector to feed the antenna.

Other voltages can be supplied through pin ANT_EXT of the

I

N connector on the front panel

(see Appendix A.6). The maximum supported current is 200mA.

Never inject a DC voltage into the MA

I

N connector as it may damage the receiver. When

using a splitter to distribute the antenna signal to several receivers, make sure that no more
than one output of the splitter passes DC. Use DC-blocks otherwise.

B.2 PPS OUT (BNC)

xPPS output (5V, output impedance 50-

Ω

). The rate and polarity of the xPPS output signal can

be speci

ﬁ

ed by the

setPPSParameters

command or on the Web

I

nterface (see Section 4.4).

The pulse duration is 5ms.

B.3 REF IN (BNC)

Use this connector to provide the receiver with an external 10-MHz frequency reference to be
used instead of the internal oscillator. The reference signal should preferably be sinusoidal
with a peak-to-peak amplitude (unloaded) ranging from 0.5V to 10V (-8dBm to +18dBm on a
50-

Ω

load).

Connecting or disconnecting the external 10-MHz reference is preferably done with the
receiver switched o

ﬀ

.

I

f the 10-MHz reference is connected or removed during operation,

the receiver will reset.

B.4 REF OUT (BNC)

This connector provides a 10-MHz output signal synchronized with the frequency reference
used by the receiver.

I

t is a sinusoidal signal with unloaded peak-to-peak amplitude of 1.1V

and output impedance of 50-

Ω

.

I

f a 10-MHz reference is fed to the REF

I

N connector, REF OUT simply duplicates REF

I

N which

allows to chain receivers using the same clock reference.

I

f REF

I

N is not used, the 10-MHz signal at the REF OUT connector is taken from the internal

receiver clock.
