The DSA815 features two pass fail limit lines, one upper and one lower. This document describes how to manually configure the upper limit line.
•   In the control menu on the front pane, press Trace/P/F
•   Select Pass/Fail

•   Switch On
•   Press Setup

•   Select Upper Limit
•   Select Edit

•   Select point 1. This is the start of the limit line. The X Axis must be non-zero. We selected 0Hz with the -20dBm amplitude for the initial low frequency portion of the limit line.
NOTE: The Keypad is a convenient way to enter the values. Just type the numbers and select the desired units.

•   Set point 2: X Axis 100MHz, Amplitude -20dBm, Connected = Yes

•   Set point 3: X Axis 100.000001MHz, Amplitude -10dBmm, Connected = Yes

•   Set point 4: X Axis 1.5GHz, Amplitude -10dBmm, Connected = Yes

•   In the control menu on the front pane, press Trace/P/F
•   Select Pass/Fail
•   Select Setup
•   Enable test by selecting Test ON
•   You can also enable Fail Stop and enable Beeper (page 2 of the setup menu)
•   You can store the limit lines internally or to an external USB stick by selecting storage, and set the filter type to Limit
