Two types of Program Headers are used in the MODEL 4045B: Instrument-control headers and Common Command and Query headers. Common Command and Query Program Headers consist of a single mnemonic prefixed by an asterisk ('*').
  • Page 71 The Program Header Separator is used to separate the program header from the program data. It consists of one or more white space characters, denoted as <ws>. Typically, it is a space. c) Program Data The Program Data represent the values of the parameters being set, for example, the '1KHZ' in the above examples.

Arguments Type: Numeric Units: S, mS, uS, nS Range: 1 uS to 10S Rounding: to 4 digits Command Type: Setting or Query Setting Syntax: TRAte<ws><value>[units] TRAte<ws>MINimum|MAXimum Examples: TRAte 10E-6 TRAte MIN Query Syntax: TRAte?[<ws>MINimum|MAXimum]...

  • Page 99: Arbitrary Subsystem

    Query Syntax: ERRor? Response: <Error number>, "<error description>" 4.9.2 Arbitrary Subsystem The Arbitrary subsystem is not part of the SCPI standard. It was developed to suit the needs of the instrument. Within this subsystem are found commands to: 1) control the point rate, start address, wavelength, and synchronization pulse address;...
  • Page 100 :STARt <numeric value> :LENGth <numeric value> :SAVe Point Rate ARBitrary:PRATe <point rate> This command is used to set the point rate. It is coupled with the frequency of the waveform by the relation: Frequency = 1/(Point Rate * Wavelength) Thus changing the point rate will result in a change in frequency.
  • Page 101 Address :ARBitrary:ADDRess <address> This command sets the current address of the waveform. It is used to determine to where arbitrary data are to be written. Arguments Type: Numeric Range: 1 to 1,000 Rounding: to integer value Command Type: Setting or Query Setting Syntax: :ARBitrary:ADDRess<ws><address>...
  • Page 102 Type: Numeric. Definite form arbitrary block. Indefinite form arbitrary block Numeric Range: -2047 to 2047 ASCII Rounding: to integer value Command Type: Setting or Query Setting Syntax Numeric: :ARBitrary:DATA<ws><numeric>{[,<numeric]} Example :ARB:DATA 100,200,1000,2000,- 2000 Query Syntax: :ARBitrary:DATA?<ws><number of points>,ASCii Response: Data are returned in the decimal numeric form.
  • Page 103 Considerations: 1) The value of the data at the start and end points must first be set by the user, using the :ARB:DATA command. 2) The range of the straight line cannot overlap with protected memory. 3) The end address must be greater than the start address.
  • Page 104 Range SIN: 16 to 1000; divisible by 4 SQU: 2 to 1000; divisible by 2 TRI: 16 to 1000; divisible by 4 NOIS: 16 to 1000, ANO: 16 to 1000, Rounding: to integer value. Scale Type: Numeric. MIN sets the scale to 1; MAX sets the scale to 100 Range: 1 to 100 (See considerations)
  • Page 105 NOIS Start Address :ARBitrary:STARt <start address> This command sets the start address of the waveform to be run. Arguments Type: Numeric Range: 1 to 999 Rounding: to integer value Command Type: Setting or Query Setting Syntax: :ARBitrary:STARt<ws><start address> :ARBitrary:STARt<ws>MINimum|MAXimum Example: :ARB:STAR 100 Query Syntax:...
  • Page 106 This command sets the length of the waveform being run. Arguments Type: Numeric Range: 2 to 1000 Rounding: to integer value Command Type: Setting or Query Setting Syntax: :ARBitrary:LENGth<ws><length> :ARBitrary:LENGth<ws>MINimum|MAXimum Example: :ARB:LENG 1E3 Query Syntax: :ARBitrary:LENGth?[<ws>MINimum|MAXimum] Example: :ARB:LENG? Response: Considerations: 1) Changing the wavelength will change either the frequency.
