The 34460A and 34461A share the same 6.5-digit Truevolt platform and measurement engine — the key difference is connectivity. The 34460A offers GPIB-only communication, making it suitable for dedicated bench setups with a GPIB controller. The 34461A adds USB and LAN interfaces, enabling integration into modern LXI-based test systems without a GPIB-to-USB adapter. The 34461A also has a slightly better DC voltage accuracy spec (0.0015% vs 0.0035%), which matters for precision calibration work. For most automated test applications, the 34461A's LAN connectivity alone justifies the upgrade over the 34460A.
