LED Operation
LEDs for the P9241/42/43A oscilloscope are described in the following table.
Inputs and Outputs
The P9241/42/43A oscilloscopes have the following inputs and outputs.
Channel 1 and 2 inputs
WARNING
A voltage source should never be connected to the ground terminals of this
instrument. If, for any reason, the Protective Conductor Terminal is disconnected or
not functioning properly and a voltage source is connected to the equipment's
ground terminals, the entire chassis will be at the voltage potential of the voltage
source, and the operator or bystanders could receive an electric shock.
LED Color When
Run state LED Green Acquisitions are running
Red Acquisitions are stopped
Amber Waiting for a single acquisition to complete
Off No driver is connected and the hardware is shut
down
WaveGen/Identify LED Blue The WaveGen output is enabled
Blinking blue The "Identify Oscilloscope" feature is on
Off The WaveGen output is disabled
CAUTION
Maximum input voltage at analog inputs
135 Vrms
50
Ω
input: 5 Vrms Input protection is enabled in 50
Ω
mode and the 50
Ω
load will
disconnect if greater than 5 Vrms is detected. However the inputs could still be
damaged, depending on the time constant of the signal. The 50
Ω
input protection
only functions when the oscilloscope is powered on.
CAUTION
When measuring voltages over 30 V, use a 10:1 probe.
