IEEE-488 Reference Programming syntax The following programming syntax information covers both common commands and SCPI commands. For information not covered here, refer to the documentation for the IEEE-488.2 standard and SCPI. Command words One or more command words make up the program message that is sent to the computer to per- form one or more operations.
Page 149 Numeric representation format: This parameter is a number that can be expressed as an integer (e.g., 8), a real number (e.g., 23.6) or an ex- ponent (2.3E6) When necessary, the Model 7001 will round real and exponential parameter values to an integer. Example: :SAV 36 Save setup in memory location 36.

Thus, to set digital input line #2 true, you must send the command with the ON or 1 parameter as follows: :SOURce:TTL2 ON or :SOURce:TTL2 1 2.

Page 154 (see Multiple command messages), the multiple response message for all the queries will be sent to the computer when the Model 7001 is addressed to talk. The respons- es are sent in the order that the query commands were sent and will be separated by semi- colons (;).
Page 155 The message exchange protocol can be summarized by the two following rules: Rule 1. You must always tell the Model 7001 what to send to the computer. The following two steps must always be performed, in this order, to send information from the instrument to the computer: 1.
Page 156: Common Commands
Common commands are device commands that are common to all devices on the bus. These commands are designated and deﬁned by the IEEE-488.2 standard. Table 5-4 summarizes the common commands used by the Model 7001 and are presented in al- phabetical order. The following detailed descriptions include programming examples using HP BASIC 4.0.
Page 157 This command issues a bus trigger which has the same 5.10.15 effect as group execute trigger (GET) command. *TST?

Page 164: Idn?  Identification Query
Description The *IDN? query command places the identiﬁcation code of the Model 7001 in the Output Queue. When the Model 7001 is addressed to talk, the identiﬁcation code will be sent to the computer. The identiﬁcation code includes the manufacturer, model number, serial number, and ﬁrmware revision levels, and is sent in the following format: KEITHLEY INSTRUMENTS INC., MODEL 7001, wwwwwww, xxxxx,/yyyyy/zzzzz...
Page 165: Opc  Operation Complete
When used with the :INITiate or :INITiate:CONTinuous ON command, the OPC bit of the Stan- dard Event Status Register will not set until the Model 7001 goes back into the idle state. The initiate operations are not considered ﬁnished until the instrument goes into the idle state.
Page 166 Enables automatic scan-list-length for channel count. Line 50 Sets a 0.5 second delay between each channel. Line 60 Starts the scan (takes 7001 out of idle state). Line 70 Set OPC bit after the scan ends. Line 80 Request value of Standard Event Status Register.
Page 167: Opc?  Operation Complete Query
When used with the :INITiate or :INITiate:CONTinuous ON command, an ASCII “1” will not be sent to the Output Queue and the MAV bit will not set until the Model 7001 goes back into the idle state. The initiate operations are not considered ﬁnished until the instrument goes into the idle state.
Page 168 IEEE-488 Reference After *OPC? is executed, additional commands cannot be sent to the Model 7001 until the pend- ing overlapped commands have ﬁnished. For example, :INITiate:CONTinuous ON followed by *OPC? will lock up the instrument and will require a device clear (DCL or SDC) before it will accept any more commands.
Page 169: Opt?  Option Identification Query
The *OPT? query command places the option identiﬁcation code in the Output Queue. When the Model 7001 is addressed to talk, the code is sent from the Output Queue to the computer. The option identiﬁcation code indicates the assigned model number for each slot of the main- frame.
Page 170: Rcl  Recall
<NRf> = 0 to 9 Memory location Description The Model 7001 can store up to 10 setup conﬁgurations in memory locations 0 to 9. Over the bus, the *SAV command is used to save setup conﬁgurations (see paragraph 5.10.11). The *RCL command is used to return the Model 7001 to a setup conﬁguration stored at one of the memory locations.
Page 171: Rst  Reset
*RST Format Description When the *RST command is sent, the Model 7001 performs the following operations: 1. Returns the Model 7001 to the *RST default conditions (see Table 5-5). 2. Cancels all pending commands. 3. Cancels response to any previously received *OPC and *OPC? commands.

Format Description The *TRG command is used to issue a GPIB trigger to the Model 7001. It has the same effect as a group execute trigger (GET). The *TRG command is an overlapped command, while GET is not. See *OPC, *OPC? and *WAI for more information.
Page 180: Tst?  Self-Test Query
The *TST? query command is used to perform a checksum test on ROM and place the coded result (0 or 1) in the Output Queue. When the Model 7001 is addressed to talk, the coded result is sent from the Output Queue to the computer.
Page 181: Wai  Wait-To-Continue
See *OPC, *OPC? and *TRG for more information. The :INIT command takes the Model 7001 out of the idle state to enable the scan function. The device operations of the :INIT command are not considered complete until the Model 7001 goes back into the idle state.
