Example 3 : dBm Measurement

Purpose: To achieve dBm measurement.

dBm is a commonly measure units which widely used in electrical, radio, mechanics,

shock and vibration, mechanical power and acoustics, and other fields, and dBm

caluation is usually used for RF signal measurement.

The programming steps:

0 *RST /*reset */

1 *IDN? /*query equipment ID*/

2 :function:resistance /*turn on 2WR measure function*/

3 :measure□AUTO /*set resistance measurement as auto*/

4 :measure:resistance? /*query the resistance*/

/*measure the reference resistance for dBm calculation*/

5 :function:voltage:AC /*turn on AC voltage measure function*/

6 :measure□AUTO /*set AC voltage measurement as auto*/

7 :calculate:function DBM /*turn on dBm calculation function*/

8 :calculate:DBM:reference □ <value> /*set reference voltage for dBm

calculation*/

9 :calculate:DBM? /*query the dBm value*/

Remark:

1. Before sending the fourth command, please connect equipment according to

resistance measure type.

2. The parameter of eighth command is the above measurement resistance.
