Clock Functions

Any TCO Option: 1st paragraph, 2nd sentence is changed:

The 1 pps output is moveable in time and can be automatically synchronized with other 1 PPS sources.

Any TCO Option: 3rd paragraph is changed:

1 pps output: There is one 1 pps output on the 5071A front panel.

Any TCO Option: 4th paragraph is changed:

The 1 pps output is TTL compatible and requires 50Ω termination. You can automatically synchronize the 1 PPS signal to an external 1 PPS, or manually change its timing by up to ± 500 ms in 50 ns steps. Use the front-panel Sync Input for an external system reference input.

Option 048: 2nd paragraph (page vii) is changed:

Power input and management: The 5071A operates from either ac or dc power. Power-source priority is controlled by the 5071A. The priority order is:

1.External dc power: when below the specified minimum voltage (40 Vdc on both dc inputs), or when absent, the 5071A switches to,

2.Ac line power.
