The real-world capacitor, resistor and inductor are not ideal, but component of complex impedance in the form of serial connection or parallel connection. The instrument calculates necessary values according to equivalent circuit connected in series or parallel. And different result will be obtained in different circuits, differing in different components.
Two equivalent modes can be conversed through some formulas, and Q and D don’t change in different modes, as shown in the above figure.
Generally speaking, component with low impedance (such as large capacitor and small inductor) is usually measured in series mode, and component with high impedance (such as small capacitor and large inductor) is usually measured in parallel mode. And the equivalent mode can be decided according to the application of component. If a capacitor is used for power filtering, series mode is the best choice, and if it’s used fo r LC oscillat circuit, parallel mode should be selected.

Chapter 5 Remote Control
TX7410 has the RS232C serial interface and the parallel GPIB (optional) interface. Both interfaces can be used to re mot ely cont rol TX7410 , but they c an not be used at the same time. The two interfaces share the same program commands, but they have different hardware configurations and different communicatio n protocols. This chapter provides the information about the two interfaces and how to use the interfaces.
5.1 RS232C Interface Introduction
The RS232C interface can be used to remotel y control the TX7410 , and it also can be used to control the DC current bias sources manufactured by our company such as TH1773/TH1775 DC current bias source. All operations from the front panel can be performed by a computer via the serial interface.
5.1.1 RS232C connection
RS232C Standard now is widely used as the s erial communication standard . RS232 stands for Recommend Standard number 232 and C is the latest revision of the standard. The serial ports on most instruments use a subset of the RS-232C standard. The full RS-232C standard specifies a 25-pin "D" connector of which 22 pins are used. Most of these pins are not needed for normal serial comm unications, and th e common RS232 si gnals are listed as follows.
TX7410 only uses the smallest subset of the RS232C standard, the signal are listed as

There may be some diff erence between TX7410 ’s RS232 interface and a sta ndar d RS232 C interface. You can make the connection cable by yourself according the diagram or order one from our company.
Note: Pin 4 and 6, pin 7 and 8 are shorted respectively at the end of controller. When the RS232C interfa ce is used to communicate with a controller, RS232 bus mode
should be selected as follows.
1) Press SYSTEM menu key, the
System Config
page will be displayed.
2) Move the curso r to t h e

field.
3) Press RS232 to select the bu s mode to R S232 bus mo de.

1) The controller sends the command using the ASCII code with NL as the end
character. TX7410 executes the command after the end character NL is received.
2) The character received by TX7410 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 TX7410 . If the controller cannot receive the character sent back by TX7410 , the reasons may be as follows.
A. The serial interface is not connected correctly. B. Check if the RS232 function is turned on and TALK ONLY function is
turned off.
C. When TX7410 is executing a bus command, TX7410 will not accept any
character through the serial interface at the same time and the character sent by controller will be ignored. In order to make sure the whole command is sent and received correctly, the character without a return character should be sent again by the controller.
3) TX7410 sends information under following two conditions. The first is when a character is received n or m a lly; TX7410 will send the character back as response . The second is when a query command is received; TX7410 will send the query response information.
4) Once a query command is received, TX7410 will send the query response information immediately e ven if the whole com mand has n ot been e xecuted. So if the command includes two queries, the controller should read the query responses twice. One query is recommended to be included in a single comma nd.
5) A query response is sent out in ASCII codes with NL as the terminal character.
6) Several query responses will be sent continuously with 1ms interval. The
controller should be ready to receive the responses; otherwise the response information will be lost.
7) The controller should receive the query response terminal character NL. Otherwise you will confuse a terminal character NL with a returned character. At the same time the controller should receive the last returned character before receiving a query response.

8) For some commands that will take a l ong time to ex ecute, f or example Correction command, the controller should keep waiting to avoid the next command being lost when TX7410 is executing the former command.
Sample Program for Serial Interface The following is a C language sa mple progra m unde r DOS en vironment . The main fun ction may be expanded by users, and the other sub functions teach you how to input or output a character string via the RS232 interface.

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 devic es conne cted on the bus ( the GPI B contr oller c ounts 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.

5.2.2 GPIB interface functions
TX7410 's GPIB functions are listed in the following table.
Code Function
SH1 Complete Source Handshake capability AH1 Complete Acceptor Handshake capability
T3 Basic Talker; Talk-Only; unaddressed if MLA; no serial poll
L3 Basic Listener; unaddressed if MTA; no Listen Only RL1 Remote/Loc a l capabil ity DC1 Device Clear capability DT1 Device Trigger capa bility
C0 No Controller capability
E1 Drivers are o pen-collector
5.2.3 GPIB addressing
TX7410 's GPIB address is stored in non-volatile memory and can be set to any address from 0 to 30 by front panel key entry in the System Config page. When TX7410 is shipped from the factory, the default GPIB address is 8. For more information, refer to “ 4.2.16 GPIB Address”.
5.2.4 GPIB bus function
TX7410 will respond to the following bus commands. ABORT I/O (IF C) ABORT I/O (IFC control line TRUE) halts all bus activity and deselects TX7410 . DEVICE CLEAR (SDC or D CL) This command can be used with an address to clear a particular device (SDC : selected device clear) or used without an address (DCL : clears all devices). The Input buffer is cleared, output data buffer is cleared and bit 4 (MAV bit) of the status byte is set to “0”, when
TX7510
receives this command. LOCAL (GTL) LOCAL returns control of a listening device to front panel control. REMOTE (RMT) REMOTE sets TX7410 to the remote mode. When this command is sent, front panel with the exception of LOCAL softkey will be disabled. TRIGGER (GET) It enables TX7410 to the TRIGGER bus command. This command may be sent to a selected device or to all devices addressed as listeners on the GPIB bus. TX7410 must first be addressed as a listener, second the trigger mode is set to the BUS trigger mode before the trigger message is sent. This command is equal to the SCPI command TRIG+FETCh? or the common command *TRG.

Chapter 6 Handler Interface
6.1 General Information
The handler interface outputs signals to indicate measurement completed, bin sorting judgments of the comparator function, and Go/No-Go judgments of the list sweep comparator function. The handler interf ace also has an input f or an e xternal trigger sig nal. Using these signals, TX7410 can easily be combined with a component handler and a system controller to fully automate component testing, sorting, and quality control data processing to increase production efficiency. Table 9-1 lists the handler interface specifications.

The electrical characteristics of the DC isolated outputs are divided into two types (See Table 6-4).
Since the power source for the Comparison Output a nd Control Output signals are different , two circuit commons (COM1, COM2) are made available.
