Arduino Library For LTC4151

LTC4151 is a high voltage I2C current and voltage monitor. It is capable of monitoring input voltage ranging from 7V to 80V with the onboard 12-bit ADC. It can also measure the high side current and an additional external voltage with the same 12-bit ADC resolution. Besides LTC4151, LTC4151-1 and LTC4151-2 have split SDA (SDAO and SDAI) for interfacing with Opto-Isolators. Continue reading ‘Arduino Library For LTC4151’ »

HP 436A Power Meter Teardown

HP 436A is a power meter capable of measuring RF power between -70 dBm and 44 dBm (roughly between 0.1 nW to 25 W) with a frequency range from 100 kHz all the way upwards to 110 GHz depending on the sensor module selected. This power meter was made in the early 70’s and has long been discontinued. Continue reading ‘HP 436A Power Meter Teardown’ »
