LF
Puts a high-pass filter and rejects the
frequency below 50kHz.

Puts a low-pass filter and rejects the
frequency above 50kHz.
Noise rejection
Rejects noise signals.
Trigger level
LEVEL
Using the trigger level knob moves the
trigger point up or down.
Configuring Holdoff
Background
The Holdoff function defines the waiting period
before GDS-1000A-U starts triggering again after
the trigger point. The holdoff function is especially
useful for waveforms with two or more repetitive
frequencies or periods that can be triggered.
Panel operation
1. Press the Trigger menu key
twice.

2. To set the Holdoff time, use
the Variable knob. The
resolution depends on the
horizontal scale.
