Hello
I am observing noise spikes in my signal data every 2 seconds (as shown in image below)
My signal conditioning setup is as follows -
Strain gauge - Quarter Bridged - 350Ohm sensor
Instrumentation amplifier - AD8428
Voltage reference of 2.5 to power the bridge - ISL21090
Bipolar power supply of +-12V (Output voltage swing between -10V to +10V) via TRACO POWER - TEN HS1
filter at 300Hz using OPA4197
Analog to digital conversion using Labjack T7 at 16 bit with measurement range -10V to +10V
I have attached the schematics of the electronic design below. Could some one please mention what i am doing wrong
