1.1 Product introduction
TH2816B is a precision LCR meter with high accuracy, good stability, and wide
measurement range. Controlled by a 16 bits MPU, TH2816B can be used for
evaluating LCR components, materials and semiconductor devices over a wide range
of frequencies (50 Hz to 200 kHz) and test signal levels (0.01 V to 2.00 V, with 0.01 V
resolution ). With its powerful function, excellent performance, perspicuous LCD
display and easy menu operation, TH2816B is suitable for high speed measurement
need on product line and high accuracy and stability measurement need in laboratory.
By using the Handler interface, IEEE488 interface (optional), and RS232C interface,
TH2816B can easily be used for automatic test system and computer remote control.
The instrument provides variable test conditions, typical conditions are as follows:
z Test signal frequency
37 typical frequency points available from 50 Hz to 200 kHz.
z Test signal level
Programmable signal level from 0.01 V to 2.00 V in 0.01 V resolution.
z Measurement speed
Fast, Medium and Slow measurement speed can be selected. Using the
averaging rate (from 1 to 255 programmable) function, you can get more stable
measurement results.
z Constant signal source output impedance
30 Ω or 100Ω selectable
z Bias current
TH2816B can control the external bias current source (for example TH1773) for
bias current list sweep measurement.
z Correction function
The OPEN, SHORT correction for correcting the stray admittance, the residual
impedance, and the other errors can be performed. The correction function has
two kinds of correction methods. In one method the open and short correction
can be performed at all of the frequency points, and in the other method the open,
short correction can be performed at the frequency points you specify.
z Test signal level monitor
The actual signal level may be different with the setup signal level. The level
monitor function allows you to monitor the actual voltage level across the device
under test or the actual current level though the device under test.
TH2816B provides 3 types of display results and 2 kinds of comparison methods
z Direct readout: The actual measurement results are displayed.
Absolute deviation (ΔABS): The difference between the measured value of
the DUT and a previously stored reference value
are displayed.
Percent deviation (Δ%): The difference between the measured value of the
DUT and a previously stored reference value are
displayed as a percentage of the reference value.
