Figure 9: Measuring Relative Power

Power Accuracy

The absolute accuracy of power measurements made with the RM meter is dependent on the power level to be measured. The RM meter does not measure power levels below -50 dBm unless the dark signal from extraneous sources (ID) is stored.

To ensure accurate power measurements below -65 dBm, store ID frequently.

The value of ID can change with temperature fluctuations.

Data Logging Using the Foot Pedal

The RM meter is supplied with a foot pedal for convenient data logging to either a computer or printer. Data logging operates at a baud rate of 2400.

To use the foot pedal:

1.Ensure the computer or printer is connected to the RS232C or IEEE 488 (GPIB) port at the back of the meter.

2.If the foot pedal is not already operational, connect the foot pedal plug to the Log jack on the rear panel of the meter.

3.Press the foot pedal. The message “Log” appears on the right-hand side of thefront-panel display, and the most recent measurements made are sent to the computer or printer through the RS232 serial or IEEE 488 (GPIB) port.

Messages and Symbols

The messages and symbols displayed by the RM meter are described in Table 7.
