ADVANCED MEASUREMENT ADVANCED MEASUREMENT Measurement item: dBm, dB, Max, Min, Relative, Hold, Compare, Math 1. Make a basic measurement Follow the procedures in the Basic measurement chapter, page 8. For measurement combinations (basic + advanced), see page 12. 2. Press the measurement key Press the measurement keys as shown below on the front panel. The measurement result will appear on the display.
GDM-8261 Quick Start Guide Compare* SHIFT/ EXIT Math* SHIFT/ EXIT The Compare measurement checks and updates if the measurement data stays between the upper (high) and lower (low) limit specified. MATH 2/4W Math measurement runs four types of mathematical operations, MX+B, 1/X, Percentage and Statistic, based on the other measurement results. For further details see the Advanced Measurement chapter in the user manual. *Please see the Advanced Measurement chapter for operation details.
DUAL MEASUREMENT DUAL MEASUREMENT Dual Measurement Combinations Combinations The dual measurement mode allows you to use the 2nd display to show another item, thus viewing two different measurement results at once.
