3.2.3 CLOCKOFFSET Adjust for delay in 1 PPS output

Format

CLOCKOFFSET <delay>

Description

This command can be used to adjust PPS output delay in nanoseconds. In timing situations, the

time delay is not a fix value attribute to two factors:

1. Signal path from the antenna to the RF, for example, using a cable with 10ns delay should

import a 10ns extra delay in PPS output

2. A signal process path delay from the RF to the digital sections, in types of different circuit

boards and signal processing method, a little different delay exists;
