3. Probe Compensation connectors:
The Probe Compensation connections provide a ground connector and 1 kHz square wave source for adjusting the high-
frequency response of a passive probe (probe compensation). The oscilloscope uses this signal to automatically
compensate supported probes. See Compensate the TPP0500B or TPP1000 probes on page 13.
You can also use the ground connector to attach an anti-static wrist strap, to reduce the chance of electrostatic damage
(ESD) while you handle or probe the DUT.
4. USB Host ports:
USB ports are located at the lower right corner of the front panel. Connect USB flash drives to which you can save or recall
data (such as instrument firmware updates, waveforms, settings, and screen captures), or connect peripheral devices such
as a mouse or keyboard.
5. Aux Trig trigger input connector:
An SMA connector to which you can connect an external trigger input signal. Use the AUX In trigger signal with the Edge
trigger mode.
6. Acq status LED:
Shows the instrument trigger/acquisition status:
■
Green - Triggered
■
Yellow - Armed but not yet triggered
■
Red - Acquisition stopped
7. Power On/Standby button:
Powers the instrument on and off. The power button color indicates instrument power states:
■
No light - No AC power applied
