The Rohde - Schwarz ESCS30 is an EMI Test Receiver. The ESCS30 really combines three measuring devices in one: a RF, a IF and a time section analyzer. And despite its compact size, its very big on features: an uninterrrupted frequency band from 9 kHz to 2.75 GHz, a LC colour display with VGA resolution, a spectrum analysis with a 10 MHz display range, memory capabilities for 30.000 measurements and a monitoring time frame that goes from 5 ms to 2 hours
