BK Precision 2120C 30 MHz Dual Trace Oscilloscope With Probes
SKU: BK-2120C
Overview
|
30 MHz Dual Trace Oscilloscope With Probes B&K Precision's model 2120C is a dual trace oscilloscope that offers high performance at a low price. Most competitor's entry level oscilloscopes have a 20 MHz bandwidth, while B&K Precision's models 2120C has a bandwidth of 30 MHz. This oscilloscope is built by and backed by B&K Precision, a company that has been selling reliable, durable, value priced test instruments for over 50 years.
