This section describes how to configure and use the load cards.
Load Card Type and Configuration ID
Each load card type is assigned a card type number as follows:
Agilent E6175A 8-Channel: Card Type is 1
Agilent E6176A 16-Channel: Card Type is 2
Agilent E6177A 24-Channel: Card Type is 3
Agilent U7177A 24-Channel: Card Type is 24
Agilent U7177A 8-Channel Heavy Duty: Card Type is 4
Agilent N9378A 24-Channel Low Resistance: Card Type is 5
Agilent N9379A 48-Channel High Density: Card Type is 6
Agilent N9377A 16-Channel Dual Load: Card Type is 7
Except for the N9378A and N9379A, each load card is equipped
with a 10-pin connector to allow assignment of a unique binary
code ID number to each card. This is useful for verifying a
particular configuration of the cards in the SLU. Refer to
Figure 5-2.
• Pin 1 is used for bit 8 on the N9377A card only
• Pins 2-5 correspond to bits 0-3, respectively
• Pins 7-10 correspond to bits 4-7, respectively
• See “Connecting Loads" for more information on addressing
loads on the N9378A load card.
