Electric and Magnetic Field Measurement NBM-520 Broadband Field Meter ♦ Available with Isotropic Probes to cover 100 kHz to 60 GHz ♦ Plug-and-Play Probe Interface with Automatic Probe Parameter Detection ♦ Fully Automatic Zeroing ♦ Extra Small and Lightweight ♦ Easy 4 Button Operation ♦ Remote Operation via Optical Link ♦ Interoperability with NBM-550 (Controller) Description The NBM-500 Series is the most accurate non-ionizing radiation survey system available. It provides the broadest frequency coverage of electric and magnetic fields. Both flat response probes and probes shaped to international standards are available. All NBM probes have a non-volatile memory containing device parameters and calibration data. Probes are calibrated independently of the meter. Any NBM probe can be used with any NBM-500 Series meter and still maintain total calibration. Applications Rugged and Lightweight Precision measurement of electric and magnetic field strength for personal Housing designed for easy safety at work where high radiation levels are present, such as: one-hand operation. • General RF Safety program measurements Interchangeable plug-and-play probes, no need for configuration. • Service work on transmitting and radar equipment • Service work on mobile antennas, broadcasting and satellite communication systems • Working with heating and hardening machines in the industry • Operating diathermy equipment and other medical instruments producing short-wave radiation • Drying equipment in the tanning and timber industries narda Safety Test Solutions an communications company USA • Germany • Italy 65 USA TEL: (1) 631 231-1700 • FAX: (1) 631 231-1711 • E-MAIL: NardaSTS@L-3COM.com • www.narda-sts.us Electric and Magnetic Field Measurement NBM-520 Broadband Field Meter Features Probe Model • Easiest 4 button operation Battery Level • Automatic probe type recognition • Intelligent probes (automatic probe data transfer) Status • Audible alarm function (threshold adjustable by PC software) Mode • Auto-Zeroing (time interval adjustable by PC software) Result • Time Averaging (time adjustable by PC software) • Spatial Averaging (discrete samples or continuously) Type of Result • Maximum Hold display function Field Unit • Calibration Due Date check by PC software NBM-520 LCD Display Description • LCD Backlight (adjustable illumination time by PC software) • Auto Power-Off (adjustable time by PC software) 2 2 • Selectable unit (V/m, A/m, mW/cm or W/m , % for shaped probes) • Hold key to freeze the current display • Optical link to connect to a PC • Remote control via optical link • Interoperability with NBM-550 (NBM-550 controls NBM-520) • PC software included for instrument setup and remote testing PC Software The NBM-TS transfer software is used for: − changing instrument settings − controlling firmware updates − performing remote controlled measurements 66 narda Safety Test Solutions an communications company USA • Germany • Italy USA TEL: (1) 631 231-1700 • FAX: (1) 631 231-1711 • E-MAIL: NardaSTS@L-3COM.com • www.narda-sts.us Electric and Magnetic Field Measurement NBM-520 Broadband Field Meter Specifications NBM-520 DISPLAY Display type Transflective LCD, monochrome Display Size 3.8 cm (1.5”), 128 x 64 dots Backlight White LEDs, selectable illumination time (OFF, 5s, 10s, 30s, 60s, PERMANENT) Refresh Rate 400 ms MEASUREMENT FUNCTIONS 2 2 Result Units mW/cm , W/m , V/m, A/m, % of Standard (“%” for shaped probes only) Display Range 0.0001% to 9999% for all units (4 digits) Result Types (isotropic, RSS) Actual (ACT), Maximum (MAX), Average (AVG), Spatial Average (SPATIAL) Averaging Time 4 seconds to 30 minutes (2 second steps), selectable by PC software Spatial Averaging discrete or continuously, selectable by PC software Alarm Function 2 kHz audible signal (4 Hz repetition), threshold adjustable by PC software INTERFACES Used for remote operation and instrument configuration, Optical Interface Serial, full duplex , 115 kBaud, no parity, 1 start and 1 stop bit Probe Interface Plug-and-play auto detection, compatible with all NBM series probes GENERAL SPECIFICATIONS Recommended Calibration Interval 24 months Battery NiMH rechargeable batteries, 2 x AA size (Mignon), 2500 mAh Operation Time 22 hours (backlight off) 16 hours (permanent backlight) Charging Time 2.0 hours Battery Level Display 100%, 80%, 60%, 40%, 20%, 10%, low level (< 5%) 5 to 95%, non condensing Humidity ≤29 g/m³ absolute humidity (IEC 60721-3-2 class 7K2) Temperature Range Operating -10° C to +50° C Non-Operating (Transport) -30° C to +70° C 5 to 95%, non condensing Humidity ≤29 g/m³ absolute humidity (IEC 60721-3-2 class 7K2) Size (h x w x d) 1.5 x 2.0 x 8 inches (38 x 52 x 203 mm) without probe Weight 10.6 oz.
