8Host Device Powering States
This test measures the ability of the Host Power Supply to remain within regulation limits with the peak current load of the CableCARD applied.
Equipment:
DUT, DC Electronic load devices, (Such as Kikusui PLZ153W or equivalent), DC Voltmeter, Ohmmeter, Sycard PCExtend 140A, quantity ≤ 25cm lengths of 22AWG cables with correct connector types.
Setup: Verify the host power cord is disconnected use ≤ 25cm length 22AWG hook up wires for the following connections.
1.) Connect the two VCC pins on J1 and J2 of the extender card to the positive terminal of the first electronic load. Connect two of the GND pins of J1 and J2 to the negative terminal of the first electronic load.
2.) Connect the VPP2 on J2 of the extender card to the positive terminal of the second electronic load. Connect two of the GND pins of J1 and J2 to the negative terminal of the second electronic load.
Connect the extender card to the Host under test.
3.) Set the electronic loads to constant current mode. Set the VCC load to 1.0A and the VPP2 load to 0.125A. (Consult the electronic load manual for operation detail if necessary.)
Plug in the Host.
Note: Due to power supply design options (regulation may be based on VCC output), it may be necessary to apply a load to VCC for VPP2 voltage test.
