Product Information
Model Name :
DLR-203

A level variation recorder capable of recording voltage variations on the same time axis as when recording signal level variations.

By simultaneously recording the level meter input 2 channels and the voltmeter input 2 channels, it is effective for failure analysis of communication lines. Diverse trigger function does not overlook the cause of failure.

Model Name :
LCK-601

This is a measuring instrument that can visualize the noise level in metal lines when replacing core wires as a tool to prevent noise-induced failures.
When a metal line failure is repaired, extremely low level noise can be measured, even though it cannot be identified through line testing using a circuit inspection tester and line test handset.

Model Name :
LM-78

This is an analog-meter-equipped level meter that can perform level measurement in a frequency range of 40 Hz to 160 kHz.
The analog meter can be very useful when the level of a measured object fluctuates significantly.

Model Name :
TMP-9701

This instrument is used to maintain ISDN lines in communication equipment and analyze their failures.
It can analyze a maximum of eight lines, including the line switching procedures of BRI and PRI lines, as well as record audio signal packets in such lines for an extended period.

Model Name :
SPM-101

This is a meter that can measure the overall transmission characteristics of a variety of carrier telephone equipment and communication devices over a frequency range of 20 Hz to 6.4 MHz.
Collectively integrating the oscillator and selective level meter unit, SPM-101 can be used for measurement by switching its selective filters with bandwidths (BW) of 6 Hz, 70 Hz, and 3.1 kHz.

Model Name :
SPM-40

This is a selective level meter that can measure the overall transmission characteristics of a variety of carrier telephone equipment and communication devices over a wide frequency band.
Collectively integrating the level meter unit and filters switchable for measurement, SPM-40 demonstrates its strong capabilities to measure the levels of signals at any frequency.

Model Name :
RSV-202

This is an instrument used to perform the high speed sampling of sensitivity output data received from radio equipment or measuring receivers, and record such data as well as the measured equipment's position information provided by GPS, or play back and display the recorded data.
Measured receiving sensitivity data files can be processed by map information software on PCs, allowing users to check the condition of radio waves received by measured devices.

Model Name :
MT-883/MT-883R

This device is a hand-held type bit error rate tester developed to achieve rapid bit error rate measurement and circuit opening testing for various types of digital data communication devices and transmission lines, and is compatible with various interfaces, test codes, and communication speeds.

Model Name :
LM-321

This is a hand-held type multifunctional level meter equipped with functions required for the testing and maintenance of voice-band transmission lines, transmission equipment, and communication devices.

Model Name :
LM-322

This is a hand-held multifunctional level meter equipped with functions required for the testing and maintenance of voice-band transmission lines, transmission equipment, and communication devices.

Equipped with an ITU-T O.41 compliant psophometer characteristics filter, band-pass filter, and band-elimination filter, LM-322 can measure psophometric noise and crosstalk, and has further enhanced functions including extended recording of measured data on multimedia cards (MMC).
