EM Eye^® 

Directional Field Strength

&

RF Signal Meter

As a field strength meter, EM Eye features miniature directional broadband antenna, frequency range of 2MHz to 2GHz, high sensitivity (down to 10mV/m), simultaneous linear and logarithmic displays, real-time bar-graph with lin/log scales and zoom, three types of detectors (average, peak and quasi-peak).

EM Eye-DL Model CTM045 provides data logging capabilities with up to 2000 data points capacity, Y2K-compliant time/date stamp and advanced data-logging features such as manual, event-based and time-based recording, averaging, etc. EM Eye-DL is equipped with RS232 interface and comes with MS Windows-based software for data exchange and software upgrades. 

Currently Unavailable Due to Redesign

• Supplied MS Windows-based software provides data exchange and viewing on PC.

• Measures Transmitter Power

• Data Logging

   EM Eye Model CTM041 measures field strength, power density and amplitude modulation. It has built-in frequency counter with high sensitivity, REF/Auto-zero and Hold functions, and a laser pointer that helps to identify the sources of emission.

TDM-200

Digital Power Meter

The Power Density Meter measures the RF field strength over the range 0.001 to 2000 µW/cm². This extremely sensitive meter can accurately measure the RF background level even in rural areas. The meter reads true power density directly on the display with 3 ranges, 20, 200 and 2000 µW/cm². For comparison, a typical cordless phone will produce about 0.01 µW/cm² at a distance of 50 feet. At FM, TV and mobile phone frequencies, accuracy, is better than 3dB. Unlike many other power meters, it has built-in antenna and detection system which yields a flat response over a very wide range of frequencies. Even at 5GHz, signals can still be measured. The meter features an internal 9v battery with a low battery indication when there is about 10 minutes life remaining.

ScanEM Near Field Probes Detect, Locate, and Measure Electromagnetic Emission to Accelerate EMC Approval

Shorten your development schedule and save money on product re-design by using the proper EMC tools at the beginning of the project.

ScanEM probes are the most versatile, and affordable instruments for detecting, locating and measuring electromagnetic emissions.

Professionals in small and large companies all over the world use ScanEM probes.

ScanEM probes will help you reliably predict EM behavior of the product and to locate emission sources in a matter of seconds. They detect the presence of an electromagnetic field and provide audio and visual indications of its relative strength. ScanEM probes can pinpoint exact sources of emission down to a single trace or component.

Connect the ScanEM-C to a spectrum analyzer and get the best performing near-field probes in the industry. With a built-in low-noise amplifier, they provide a strong broadband output signal that allows you to see what you have been missing using passive probes. One of ScanEM's unique advantages is flat frequency response that provides accurate information about spectral content of the signal

As ultra-wide bandwidth, non-contact voltage and current probes for an oscilloscope, ScanEM-C will reveal previously invisible transients. ScanEM-HC H-field probe uniquely enables you to observe current waveforms in traces or even ground plane without affecting your board.

As an EM field probe for a multimeter, ScanEM-C will provide DC voltage that is a function of the field strength.

ScanEM-QC probes were originally designed for, and in cooperation with, the FCC in order to enable their inspectors to check for violators of rules in the field. After their successful test and adoption of the probes for FCC use, now these probes are available for engineers, technicians and QA inspectors to test their products the same way the FCC does.

PLIP

Power Line Interference Probe 

Compliance
The PLIP is designed to comply with the CIPR16 requirements for a voltage probe. The design incorporates several features that are in addition to the basic CISPR16 specifications.
These offer three major advantages:

Safety Complete galvanic isolation for protection against line voltages.

Sensitivity The PLIP incorporates a 30dB RF amplifier. This results in a nominal antenna factor (insertion loss) of 0dB, against that of a 'conventional' voltage probe of 30dB.

Protection The PLIP features signal filtering with transient limiter and output clamping. The net result is that any analyzer or receiver connected to the output of the PLIP is protected against damage due to high or transient signal conditions.

Sensors

Monitoring of the Signals from Transmitters and on Data Cables with Model CTC112 and Model CTC116

Active remote broadband sensors models CTC112 (radiated emission - E-field) and CTC116 (conducted emission) allow for measurement and monitoring of electromagnetic fields in remote locations. Each sensor has built-in low-noise preamplifier with ~15dB of gain and drives standard 50 Ohms input of any test equipment, such as spectrum analyzer, oscilloscope, etc.

EMAlert®

EMI Monitor

EMAlert^® Model CTC022 and Model CTC026 modules installed inside of critical equipment continuously monitor emission level, as well as its amplitude modulation since the latter can cause more damage that steady field. Until the level of EMI exceeds preset level (user-set), EMAlert^® modules are just passive observers. The moment the interference exceeds the preset level, however, EMAlert^® module sends signal that the EM Event^TM has occurred and then begins to probe the host equipment by sending pulses every 3ms. The host equipment is supposed to respond with similar pulses if it continues to function properly. Should the host fail to respond, EMAlert^® issues Equipment Failure signal and, if desired, attempts to reset the host.

  RF Hazard Detector

LHS-100

RF Hazard Detector

Laplace has developed a new product specifically for the mobile phone and other telecoms industries. Worldwide, cell phone transmitters and other communication transmitters are now being located in 'street furniture' to avoid planning restrictions. These sites include, street lighting poles, inside petrol (gas) station signs, rooftop sites and other ‘stealth’ sites.

A self contained, independent system which monitors the activity of a transmitter and gives clear indication when the site is safe for work.

The LHS-100 system provides a simple and clear protection for all mobile phone, stealth sites and telemetry sites that may require access by non-qualified personnel

 Professional Version

RF Detector

Radio / microwave alarm is the size of a small pager, just 5.7cm x 4cm x 2cm. The high sensitivity version is ideal for anyone who needs to find out exactly what is emitting radio or microwaves, including hidden sources. An industrial version is triggered by higher levels of radiation and is ideal for personnel alarm use when working near transmitters or RF sources.

The alarm provides an audio output that bleeps when the pre-set level is reached, the frequency of the bleeps increases if the signal level increases.

The sensitive version will detect a typical mobile phone base station from 100 meters, a mobile phone at 6 meters and a microwave oven at 3 -10 meters. The sensitivity can be adjusted to suit the application with a small adjustment knob.
