Do not use spaces within a parameter, or within a number. Multiple Parameters When a command has more than one parameter, separate the parameters wit

3、h commas. For example: OUT 1 V, 100 HZ. Numeric Parameters Parameters may have up to 255 significant figures. Exponents may range from -32000 to +32000. The useful range for 5720A programming is 2.2 E-308 to 1.8 E308. Case Sensitivity All lower case letters are converted to upper case except in quot

4、ed strings. Extra Parameters Avoid using extra parameters. Too many parameters will cause a command error. Null Parameters Null parameters will cause a command error (e.g., adjacent commas in CLOCK 133700, ,071787). Expressions Do not use expressions as parameters. An example of an expression is (4+

5、2*13). Units Accepted units in command parameters are: A amperes DB decibels DBM decibels references to 1 milliwatt for ac voltage amplitude HZ hertz OHM ohms PCT percent PPM parts per million V volts 4 Syntax Rules (continued) Multipliers MA mega, or unit x 1,000,000) K kilo, or unit x 1,000) M mil
