Program Comments

10: Assign the source’s HP-IB address to a variable.

20 to 50: Abort any HP-IB activity and initialize the HP-IB interface.

60:Set the source to its initial state for programming. The *RST state is not the same as the PRESET state. For complete details of the instrument state at *RST, see “SCPI Command Summary," in Chapter 2.

70:Select the frequency mode to be SWEEP instead of the default sweep mode of “CW” that was selected with *RST.

80:Set the source start frequency to 4 GHz.

90:Set the source stop frequency to 7 GHz. Note the optional usage of the short-form mnemonic, “FREQ”.

100:Set the source’s power level to -5 dBm.

110:Set the sweeptime to 500 ms. Notice that upper/lower case in commands does not matter. Also spaces before the suffix (“MS”) are not required in SCPI.

120 and 130: Set markers 1 and 2 to a fixed value. Notice that the value for marker 2 does not end with a frequency suffix. Hertz is a default terminator and is understood.

140:Wait until the source has completed setting up the commands that have been sent so far before turning on the output.

150:The ENTER statement causes the program to wait here until the source responds to the previous *OPC? with a ‘1’.
