Page 65: Using The Instrument
LOCAL OPERATION Using the instrument Precautions Microwave connectors Care should be taken when using microwave connectors, both on the instrument and any accessories that are used, such as cables, adapters, attenuators, etc. Complying with the following precautionary notes will ensure longer component lifetime and less equipment downtime due to connector or component failure.
Page 66: Leveling
Leveling is used to control the power level of the instrument’s RF source, via a fast, closed-loop feedback system. The control (feedback) signal used to level the output can be derived from either the internal leveling detector of the 6810A Series, or from an external detector or power meter, connected to the rear-panel EXT LEVEL INPUT Internal leveling provides a constant signal at the SIGNAL SOURCE OUTPUT connector regardless of reflections by adjusting the level of the source, thus improving the source match.

Page 135: Introduction
GENERAL INFORMATION Introduction 6810A Series instruments are equipped for remote operation via the GPIB interface or the RS-232 (serial) interface. The GPIB (General Purpose Interface Bus) interface provides instrument control with full talk and listen capability. The command syntax for both GPIB and RS-232 conforms to IEEE 488.2.
Page 136: Compound Headers
GENERAL INFORMATION Compound headers Compound headers allow a complex set of commands to be built up from a smaller set of basic elements in a "tree" structure. The elements of a compound header are separated by a colon " : ". Each subsystem in this instrument is organized as a separate tree structure.
Page 137: Default Branches
GENERAL INFORMATION Default branches Some elements within the compound header tree structure are enclosed within square brackets, " [ " and " ] ". These elements may be omitted, if desired, to reduce the length of the compound header. Abbreviations In general, compound header elements have a long and a short form.
Page 138 'This string contains the word ''Hello''' will be interpreted as the string: This string contains the word 'Hello' When receiving string data, the 6810A Series GPIB system interprets character codes as follows: 32 - 126 Standard ASCII characters Copyright symbol ©...
Page 139: Response Data
GENERAL INFORMATION Note that data received from the instrument as <DEFINITE LENGTH ARBITRARY BLOCK RESPONSE DATA> is already in a form suitable for transmission back to the instrument as <ARBITRARY BLOCK PROGRAM DATA>. The definite length form can be used on both GPIB and RS-232 interfaces.
Page 140 GENERAL INFORMATION <NR2> This type of numeric response is used to return real numbers; it includes an explicitly placed decimal point, but no exponent. The decimal point will always be output, with at least one digit before and one digit after the decimal point. A negative number will be preceded with a − sign; a positive number may or may not have a + sign.
Page 141: Terminating Commands
GENERAL INFORMATION Terminating commands GPIB A <PROGRAM MESSAGE TERMINATOR> (as defined in IEEE 488.2) can be a line-feed character (ASCII 10), a line-feed character with the ^END message asserted at the same time, or an ^END message asserted with the final character of the <PROGRAM MESSAGE>. The terminator may be preceded by any number of "white space"...
Page 142 GENERAL INFORMATION Valid values Describes the type of number for numeric parameters, e.g. real or integer, and the allowable range, if applicable. If a parameter is defined as character program data, the allowable <CPD> strings are given. For string program data, the maximum number of characters is specified. In the above example, the first parameter can accept the strings A, B, C or RX;...
Page 143: Status Reporting
GENERAL INFORMATION Status reporting The instruments within a GPIB system contain a set of registers that reflect the current state of the instrument and whether a particular event has occurred. It is also sometimes necessary for an instrument to generate an alert if that condition exists or if that event has occurred. The instrument's status registers contain information about the condition of the instrument.
Page 144 GENERAL INFORMATION Operation Status Register. This is a 16-bit register, defined in SCPI, which further extends the status reporting structure by providing information about what the instrument is doing. It is read by the STATus:OPERation:CONDition? command. The summary bit output of the register is recorded in bit 7 of the Status Byte.
Page 145 GENERAL INFORMATION 1. Determine which register set and which of its bits monitors the condition. 2 Determine how that bit reports to the request service (RQS) bit of the Status Byte (some report directly while others may report indirectly through other register sets). 3.
Page 146: Getting Started
This section provides an introduction to GPIB programming of the 6810A Series. The remote operation command set The first point to notice when controlling the 6810A Series remotely is that there is no straightforward mapping between manual front panel operations and their remote command equivalents.
Page 147: Preparing The 6810A Series For Gpib Operation
Connection to the external controller is made via the rear panel GPIB connector. The 6810A Series GPIB system can operate in two modes, controller or talker/listener. In controller mode, the instrument takes control of the bus in order to drive an external source. This mode is selected by pressing the [No External Controller] soft key.

Page 299 ERROR MESSAGES Character data not allowed Remote control error. Character data was received but is not allowed by the instrument at this point. Command header error Remote control error. An error was detected in the header. This error is displayed when the instrument cannot detect more specific errors.
Page 300 ERROR MESSAGES Invalid date An invalid date was entered. This could result from attempting to set the month to a number greater than 12, entering an invalid day for the month (for example February 31), or entering a year before 1980 or after 2099. Invalid directory Remote control error.
Page 301 ERROR MESSAGES Password out of range An out of range value was entered when attempting to set up a user-defined password. Valid ranges for passwords are: Level 1: 1000 to 9999Level 2: 100000 to 999999 Security: 100000000 to 999999999 Passwords do not match The value entered to confirm a password change was not the same as the value originally entered.

Page 307 GPIB STATUS REPORTING STRUCTURE Notes The default transitions listed above are those set at power on and when :SYSTem:PRESet is received. Note that the Operation Status Enable Register is cleared to all zeros at power on and on receipt of :SYSTem:PRESet so it is necessary to enable the appropriate bits before the summary bit in the status byte register will be enabled.

Page 310 Appendix D NUMERIC ENTRY HANDLING All commands that take a NUMERIC VALUE must also accept the following special forms of numbers: MINimum Set the parameter to be the smallest value that can be settable for that parameter, i.e. the value nearest to negative infinity. MAXimum Set the parameter to be the largest value that can be settable for that parameter, i.e.

Page 316 Appendix G EMULATION OF IEEE488.1 ON THE SERIAL INTERFACE Since the RS-232 interface does not have the extra control lines that the IEEE488.1 interface possesses, it is necessary to emulate the extra functionality. This is done using two mechanisms: the first is the break facility and the second is by sending specific control codes over the RS232 interface, which are interpreted to mean specific IEEE488.1 behavior.
