7 Low and Full Speed Tests Droop/Drop Test The Drop test is a measure of a hub’s ability to host full load current while keeping the output voltage above spec. To perform this test, VBUS is measured with all downstream ports loaded with 500 mA loads (for host and self powered hubs) or 100 mA loads (for bus powered hubs). The lowest value measured across all ports must be between 4.75 V and 5.25 V for host and self powered hubs or it must be greater than or equal to 4.4 V for bus powered hubs.
Low and Full Speed Tests USB Power 7 DS1 There are several switches/buttons that are used for general control of the test fixture. These include (see picture below): • Switch S5 allows you to select either the Droop or Drop test. • Switch S4 allows you to select either the 100 mA or 500 mA load. • Press and hold S1 for at least three seconds to turn the test fixture on. • While pressing and holding S2, press S1 to turn the test fixture off.
