FEATURES 

The Narda Broadband Meter NBM-520 is designed for on-site use. The 
concept focuses on simple operation and the range of functions has 
been deliberately kept to the main features necessary for performing 
precision field measurements. 
 

Display and operation 

 

Operated by weatherproof foil keypad using just 4 buttons  
with perceptible click point 

 

Backlit monochrome LCD with selectable illumination time,  
easy to read even in bright daylight 

 

Result display and evaluation 

 

4 measurement modes selectable using the Mode button: 
Instantaneous value (ACT) 
Maximum (MAX) 
Time average (AVG) 
Spatial average (SPATIAL) 

 

Display units selectable using the Units button:  
V/m, A/m, mW/cm

Hold button for “freezing” the display value 

 

Automatic adjustment, application of calibration data 

 

Intelligent probe interface recognizes the NBM probe type and 
automatically imports and applies the correction values stored 
in the probe during calibration 

 

Fully automatic zero point adjustment with user definable time 
interval 

 

Warning functions 

 

Audible and visible warning signals for high field strengths:  
Alarm threshold can be set from a PC 

 

 

Everything at a glance. The clearly arranged 

display is easy to read. 

The optical interface connector and AC 

adapter / charger connector compartment is 

sealed with a rubber cap. The tilt stand 

provided in addition to the tripod bush can be 

used to place the instrument securely on a 

flat surface.
