Option E - Event Marker; Option X - External Frequency Reference; Option M - Remote Monitoring; Option F - Fast Data Output - ashtech Z-Xtreme Operations & Reference Manual

Option E - Event Marker

The E option enables the storage of event times created from a trigger signal. The
receiver measures and records event times with high accuracy (down to one
microsecond). The receiver stores an event time at the rising edge of the trigger signal
(or the falling edge on command) and the time is recorded in the receiver's PC
memory card and/or output through the TTT NMEA message.

Option X - External Frequency Reference

The external frequency option X allows you to input an external frequency so you can
synchronize receiver data to an external clock. When enabled, its installation disables
the internal oscillator and uses the external frequency input only.

Option M - Remote Monitoring

The remote monitoring option allows you to use the
control the receiver via a modem from a remote location.

Option F - Fast Data Output

This option enables the receiver to be programmed to output both raw position data
and NMEA messages or record data (if a PCMCIA card is present in the receiver) at
user- selectable frequencies up to 10Hz. Without this option, only frequencies up to
5Hz are available.

Option T - Point Positioning

The T option allows you to put the receiver into point positioning mode using the
$PASHS,PPO command. Point positioning mode improves the accuracy of an
autonomous position of a static point.
Option 3 - Observables—1, 2, 3
This option determines the observables available in the receiver where:
1—CA code and P-code on L1/L2 (no carrier)
2—CA code and carrier, P-code on L1/L2 (no carrier)
3—CA code and carrier, P-code on L1/L2 and carrier
