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 :
LM-534B

There are cases where multiple channel signals (specified by frequency bands) are multiplexed to be transferred on a single transmission line of remote monitoring and control equipment, telemeters, etc.
When the signal levels of a specific channel are measured on such transmission lines using an ordinary flat level meter, signals on the other channels must be stopped.
However, LM-534B enables easy measurement of the signal levels of a specific channel without stopping signals on the other multiplexed channels.
Further, the signal-out function (signal output) enables the signal output from a specific channel, thereby allowing the monitoring of a specific channel for an extended period by concurrently using a level variation recorder.
