  • Page 4: Chapter 1 General Introduction

    TH2817B is a precision LCR meter with high accuracy, good stability, and wide measurement range. Controlled by a 16 bits MPU, TH2817B can be used for evaluating LCR components, materials and semiconductor devices over a wide range of frequencies (50 Hz to 100 kHz) and test signal levels (0.1V, 0.3V, 1V).

  • Page 40: Chapter 5 Remote Control

    TH2817B has the RS232C serial interface and the parallel GPIB (optional) interface. Both interfaces can be used to remotely control TH2817B, but they can not be used at the same time. The two interfaces share the same program commands, but they have different hardware configurations and different communication protocols.

  • Page 42 TH2817B executes the command after the end character NL is received. The character received by TH2817B will be sent back to the controller again. The controller will not send the next character until the last return character is received correctively from TH2817B. If the controller cannot receive the character sent back by TH2817B, the reasons may be as follows.
  • Page 43 For some commands that will take a long time to execute, for example Correction command, the controller should keep waiting to avoid the next command being lost when TH2817B is executing the former command. Sample Program for Serial Interface The following is a C language sample program under DOS environment. The main function may be expanded by users, and the other sub functions teach you how to input or output a character string via the RS232 interface.
