Front Panel Overview Introduction to the Agilent 81133A/81134A Pulse Generator

Agilent 81133A/81134A Pulse Generator User’s Guide, January 2005 17

LEDs The front panel of the 81133A/81134A pulse generator contains the

following L EDs:

LED Description

Unlock When this LED is lit, the frequency entered for the external clock

does not match the actual input from the externa l clock. In this

state, the internal PLL is not locked and the instrument's outputs

may not be within specification.

You have to either reenter the frequency of the external clock, or ex-

ecute the Measure function. See “Clock Sources” on page 73 for

details.

Active When lit, indicates that the instrument is either in external or direct

external clock mode. A valid external clock signal has to be applied

to the clock input.

If not lit, the internal clock source is used.

Armed Indicates that the instrument is waiting for a signal at the Start In-

put.

When the specified signal arrives, the instrument starts generating

signals.

Port LEDs Indicate the status of the port. When the LED is lit, the port is

active.
