Multifunctional Level Variation Recorder
New
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.

Analog Level Meter
New
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.

Measuring Instrument for Transmission Characteristics
Model Name :
MS-302

This is a measuring instrument for evaluating the overall transmission characteristics of a variety of carrier telephone equipment and communication devices (successor of the MS-301 measuring instrument for transmission characteristics).

Detail
Variable Resistor Attenuator
Model Name :
AT-50

This device is a variable resistor attenuator with a maximum attenuation of 61 dB when operated in the frequency band of DC to 3 MHz (DC to 200 kHz when Z = 600 Ω).
