When you run this VBA program, reset is performed, the GPIB address of

the power meter to be controlled and the measurement conditions of the

E5071C are set, and the message "Do you want to zero and calibrate the

power sensor?" is displayed. If you want to execute the zero adjustment

and the calibration of the power sensor, click Yes, otherwise click No.

If you want to execute the zero adjustment and calibration of the power

sensor, follow the displayed messages to connect the power sensor

connected to the A channel of the power meter to the POWER RF port of

the power meter and click OK. When the zero adjustment and calibration

of the power sensor is complete, the message "Zeroing and calibrating the

power sensor is complete" is displayed.

When a message that prompts you to connect the power sensor to port 1

of the E5071C is displayed, make the connection and then click OK. The

power calibration data measurement is executed immediately and the

obtained power calibration data array is saved in a file named

Lines 100 to 150

Assign the sweep type (power sweep), the number of points (41), the

power range (-20 to +12 dBm), the sweep start value (-20 dBm), the

sweep stop value (-10 dBm), and the fixed frequency (1 GHz) to the

Swp_type, Nop, Pow_rang, Start_p, Stop_p, and Cw_freq variables,

respectively.

Lines 160 to 170

Assign the number of power calibration data measurements for each

measurement point (4) and the limit value of the power calibration data

array (10 dBm) into the Num_avg and Limit variables, respectively.

Returns the E5071C to the preset state.

Sets the power meter's GPIB address (13) in the E5071C.

Lines 260 to 310

For channel 1, these lines assign the sweep type to the Swp_type variable,

the number of points to the Nop variable, the power range to the

Pow_rang variable, the sweep start value to the Start_p variable, the
