STROBE-M is a TEM and IP receiver, that digitally records the input voltage taken from the receiver loop or potential electrodes. It is based on a 16-bit ADC and an Analog Devices signal processor.
STROBE receiver takes voltage readings at a number of time moments during the on- or off-time. These readings are actually the average voltages at the integration intervals (so called strobes), the middle of the interval is considered a reading time moment. Receiver provides setting an appropriate measuring time scale. The whole measuring time interval in STROBE receiver can be divided in two stages: the early and the late stage (see transmitter and receiver diagram). Different linear time scales for early and late stages can be set, that is made for more detailed study of initial stage of decay.
Synchronization of the receiver and the transmitter in the TEM mode is performed via the synchronization cable. In the IP mode synchronization can be either autonomous (on the input voltage drop), or external (via the synchronization cable).

 

Transmitter and receiver diagram

 

The receiver is controlled by a computer connected via RS-232C serial interface. Beside the computer supplied together with the instrument (Palmtop type computer with Windows CE OS), any notebook type computer with OS Windows 98 or later and RS-232C standard serial interface can be used as a control one.
Receiver control program provides setting the measurement parameters, start-up of measurement in the selected mode, visualization of measurement results and generation of data files.
