Official 34970A/34972A family reference for 34970A. The 34970A is the rear instrument; the foreground 34972A has different LAN/USB interfaces. Multiple instruments and plug-in modules are illustrative and are not established as included.
Official E36102B reference photo with the original English feature callouts retained. The E36102B label is legible; line-voltage selection and fitted configuration still require unit verification.
Official E36300 family reference for E36312A showing E36311A, E36312A, and E36313A together. The photograph represents the product family and does not mean that three supplies or optional interfaces are included.
Official N6700C-series family reference for N6700C, pictured N6701C 600 W mainframe. The catalog N6700C is rated 400 W; the pictured rating must not be attributed to the offered model.
Official N6700 basic-module family reference for N6731B. The source explicitly groups N6730, N6740, and N6770 modules as the basic series; the pictured module label is not sufficiently legible to claim an exact N6731B photograph.
