With regards to EMC, these devices are declared as class B, suitable for residential or business environment.
- Page 5 Statement 0001/WARNING: The power supply provided by Septentrio (if any) should not be replaced by another. If you are using the receiver with your own power supply, it must have a double isolated construction and must match the specifications of the provided power supply.

_____________________________________________________ 1 PolaRx4_PRO and PolaRx4TR_PRO 1 PolaRx4_PRO and PolaRx4TR_PRO Rear Panel Connectors The rear panel features the following connectors (PPS IN only available on PolaRx4TR_PRO). 1.1.1 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. -

_____________________________________________________ 1 PolaRx4_PRO and PolaRx4TR_PRO Never inject a DC voltage into the MAIN 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. -

- Page 10 _____________________________________________________ 1 PolaRx4_PRO and PolaRx4TR_PRO When the PPS OUT signal is configured, the PPS-IN-to-measurement-latching delay is the delay between the leading edges of the pulses on the input 1 and input 2 ports of the oscilloscope. The oscilloscope trigger level should be set to 1V. To avoid possible 20-ns jumps when power-cycling the receiver, the transition zones (gray bars in the figure on the previous page) should be avoided.

Waking up from stand-by mode is done by sending characters to the COM1 serial port. For remotely-operated receivers, make sure that COM1 is remotely accessible before putting the receiver in stand-by mode.

Page 17: Pseudorange Inter-Frequency Biases
_____________________________________________________ 1 PolaRx4_PRO and PolaRx4TR_PRO 1.10 Pseudorange Inter-Frequency Biases The figures below show the nominal receiver pseudorange inter-frequency biases (IFB) as a function of the carrier frequency. The bias at the L1/E1 carrier frequency (1575.42MHz) is taken as a reference and is therefore arbitrarily set to 0. -
Page 18: Hardware Specifications
_____________________________________________________ 1 PolaRx4_PRO and PolaRx4TR_PRO A positive value of the IFB at frequency F means that the pseudorange at that frequency will be larger than the pseudorange at L1/E1, even in the absence of any ionospheric divergence or satellite bias. For example, the second graph shows that the receiver introduces about 2.4m bias in the GPS L5 pseudoranges compared to the GPS L1 pseudoranges. -
