WY2271 Type RF Millivolt Meter (Ultra High Frequency Millivolt Meter)Detailed product description：

Characteristics of WY2271 RF Millivolt Meter (Ultra High Frequency Millivolt Meter):

Using only one probe to achieve ultra wide frequency response: 1kHz to 1.5GHz.  
Exceeding the frequency response characteristics of similar millivolt meters; The frequency response index of low level (<30mV) is consistent with that of high level.  
Highly reliable keycap style tactile range switch, with no worries of slipping or misalignment.  
High quality probes with strong interchangeability.  
Normalize the linear scale for easier reading.

Two main technical specifications:
