Hi,
The main instrument (2790 SourceMeter Air Bag Test System) is actually still available. However, the 2790-HH model is obsolete. Instead, the available model options are below. There is no longer an option that comes with two modules. They only come with one module, so a second module would need to be added to the quote.
Models:
2790 SOURCEMETER SWITCH SYSTEM MAINFRAME ONLY
2790-A/E SOURCEMETER SWITCH W/1 HI V CARD 1M OHM - 7753
2790-H SOURCEMETER SWITCH W/1 HI V CARD 10M OHM - 7702 (double checking this).
2790-H/E SOURCEMETER SWITCH SYSTEM WITH ONE HIGH - 7751
2790-L/E SOURCEMETER SWITCH SYSTEM WITH ONE LOW V - 7752
Modules:
7702 40-channel General Purpose Multiplexer Module
7751 High Voltage Source/Switch Module
7752 Low Voltage, Current-Source-Only Source/Switch Module
7753 1MW High Voltage Source/Switch Module (The Model 2790 supports only one Model 7753.)
