10 Channel PPS Source - Atomic Holdover Option NR2310-P/G
NR2310-PG ID-27

10 Channel PPS Source

NR2310-P/G

Ten transient and fault protected PPS outputs with < 2 ns of channel skewing. Each channel is monitored and status displayed on the front panel. Built-in self-test drives a signal that can be tied into an alarm panel.  Atomic holdover option holds PPS drift to less than 1 usec/hour ideal for GPS unstable environments.10 MHz frequency reference output available to stabilize local oscillators.

● Ten fault and transient protected outputs.

● Ten channels frequently eliminate the need for a distribution amplifier.

● Channel skewing < 2 ns.

● Drives 3.3 Vdc LVCMOS or 5 Vdc into 50 Ohms

● PPS accuracy < 1 Sigma 15 ns

● Optional 10 MHz low noise GPS locked output.

● Available as an atomic PPS source for GPS denied environments.

NMEA/PPS Source- with Selectable Timing Sources GNSS, Serial Data or OCXO Holdover
NP3001 ID-63

NMEA-PPS Master Timing Source with Prioritize Timing Source

NP3001

The NP3001 accepts timing information from either an embedded GNSS receiver or an external NMEA/PPS source. Each source can be prioritized. Once synchronized the unit will produce NMEA and PPS from the selected source. If all sources fail, the unit becomes a simulator based upon its internal OCXO. Battery backup allows the unit to be synchronized and then used to bring timing information into a GNSS denied environment. Front panel display provides equipment status and facilitates the equipment configuration. The 26 Channel GNSS receiver quickly acquires and can be programmed to produce a PPS pulse once an accuracy level has been achieved or to produce a PPS from a TCXO source continuously. NMEA data streams can be programmed to content and baud rates. The unit may also be powered from a DC source or a Novus power adapter.

  • GNSS lock indicator and built in self test
  • PPS accuracy 15 ns @ 1 sigma.
  • 26 Channel GNSS receiver
  • PPS pulse programmable in 1 ms increments.
  • Cable delay compensation
  • Operates from DC Power in three ranges +- (10 to 18, 18 to 36, 36 to 65) VDC or an AC Adapter
  • Accepts timing from the GNSS receiver or an external NMEA/PPS source

Kits are available that include antenna, cables and power supply. Several features can be customized at the factory – frequencies other than 10 MHz either from a unique crystal or with a built-in synthesizer that is GNSS-locked. Time stamping capability to 100ns resolution. To meet unique requirements, we have shipped product with output features requiring a custom amplitude, square wave output, high voltage and high current drive.
