Perform the following steps to realize the DC bias current list sweep measurement.
1) Only on the List Sweep page, TH2816B has the capacity to control the DC Bias
Current Source via the RS232C interface.
2) Connect TH2816B and TH1773 according the above diagram.
3) Set TH2816B’s bus mode to iBIAS mode. Press SYSTEM menu key, the System
Config page will be displayed. Move the cursor to the BusMode field, and use
the softkey iBIAS to set the bus mode to iBIAS mode.
4) Set TH1773’s serial function to ByLCR mode (Refer to TH1773 user manual.).
5) Set a list sweep measurement limit table on the List Setup page, and perform the
measurements on the List Sweep page.
When perform the DC bias current list sweep measurement, delay time should be set
in order to get stable measurement results.
SEQ or STEP sweep mode can be selected.
5.2 GPIB Interface Introduction
5.2.1 GPIB Connection
When configuring a GPIB system, the following restrictions must be adhered to.
The total length of cable in one bus system must be less than or equal to two
meters times the number of devices connected on the bus (the GPIB controller
counts as one device) and the total length of cable must not exceed 20 meters.
A maximum of 15 devices can be connected on one bus system.
There are no restrictions on how the cables are connected together. However, it
is recommended that no more than four piggyback connectors be stacked
together on any one device. The resulting structure could exert enough force on
the connector mounting to damage it.
Figure 5-1 shows a GPIB interface connector.
