ETM770 is a handheld battery powered signal strength meter used in the field to measure the signal quality of all mobile operators available in 2G, 3G, 4G, Cat M1, NB-IoT (GSM, UMTS and LTE) bands, depending on the model selected.

ETM770-10 version (OLED Screen):

  • Sixteen Bands LTE FDD CatNB2/CatM1: B1/B2/B3/B4/B5/B8/B12/B13/ B18/B19/B20/B25/B28/B66/B71/B85
  • Quad Band GSM: 850, 900, 1800 and 1900 MHz

ETM770-7 version (OLED Screen):

  • Twelve Bands FDD-LTE: 700, 800, 850, 900, 1700/2100 (AWS), 1800, 1900, 2100, 2600 MHz (bands 1, 2, 3, 4, 5, 7, 8, 12, 18, 19,20, 28)
  • Seven Bands UMTS (WCDMA/FDD): 800, 850, 900, 1700/2100 (AWS), 1800, 1900 and 2100 MHz (bands 1, 2, 4, 5, 8, 9, 19)
  • Quad Band GSM: 850, 900, 1800 and 1900 MHz

In order for communication via the mobile network to function satisfactorily it is required that the signal quality at the site is adequate and stable. With ETM770 you only need a SIM card to be able to view the signal strength of all available operators. You can also do test broadcasts to test the GPRS/UMTS/LTE connection. ETM770 is an ideal tool for field installations in order to verify and optimize the signal quality and secure wireless communication between applications and systems.
