The "TMP-9701" is a measuring instrument used for the maintenance and fault analysis of ISDN lines in communication equipment. It can analyze circuit-switched procedures for up to 8 lines in both BRI and PRI, and it allows for long-term recording of voice signal packets. The call recording function can record up to 184 channels for more than 2 months. Additionally, the use of an LCD display and a touch panel enables easy operation for measurement settings and data analysis. 【Features】 ■ Up to 8 BRI or PRI lines can be connected and measured simultaneously. ■ Each of the 8 lines can be selected as BRI or PRI. ■ The call recording function can record up to 184 channels for more than 2 months (when using 8 PRI lines). ■ Recorded data is separated into Lch./Rch. for transmission/reception, allowing for effective detailed analysis of voice signals. *For more details, please refer to the PDF document or feel free to contact us.

The "RDV-202" is a measuring instrument that records and displays the reception sensitivity output of radios and measuring receivers through high-speed sampling, along with GPS location information. The measured reception sensitivity data files can be plotted as markers on a computer map, allowing for the creation of area maps. Additionally, it enables long-term evaluation and analysis of the fading phenomenon that affects the quality of wireless communication. 【Other Features】 - Adoption of a large display and touch panel - Measurement data is saved in built-in non-volatile memory - Measurement data can be output in CSV format, making it usable with spreadsheet software - Remote operation via network is possible - Data transfer to a computer is possible via USB memory and Ethernet *For more details, please refer to the PDF document or feel free to contact us.

The "WT-920" is a handheld testing device compatible with the specific low-power 920MHz band LoRaWAN for the Japanese market. It can perform connection confirmation tests to existing networks as a LoRaWAN end device and measure the propagation characteristics of specific sections using LoRa modulation on its own. It is highly effective for preliminary investigations in network construction and for identifying causes during malfunctions. 【Features】 ■ Capable of connection testing for LoRaWAN networks ■ Can measure PER (Packet Error Rate) in direct communication with the device ■ Can display a list of RSSI (Received Signal Strength Indicator) ■ Records location information via GPS along with RSSI measurement results ■ Data can be saved to a memory card with a maximum capacity of 2GB *For more details, please refer to the PDF document or feel free to contact us.

The "SPM-101" is a transmission characteristic measurement device capable of measuring the characteristics of various transport devices and communication equipment across a frequency range of 20Hz to 6.4MHz. It integrates an oscillator and a selective level meter, allowing for the use of selectable filters with bandwidths (BW) of 6Hz, 70Hz, and 3.1kHz. With a maximum input level of +40dBm for 75Ω unbalanced connections, an external attenuator is not required. 【Features】 ■ Equipped with an oscillator and a selective level meter (frequency settings can be selected to be linked or unlinked) ■ Bandpass filters (BPF) with three bandwidths: 6Hz, 70Hz, and 3.1kHz ■ The level meter display consists of an analog meter plus a digital display ■ No external attenuator is needed with a maximum input level of +40dBm for 75Ω unbalanced connections *For more details, please refer to the PDF document or feel free to contact us.
