* '''''Manual errata:''' In manual 070-1583-01, Fig. 4.3 Output Delay Range Check (p. 4-5), the PG 505 connections are drawn correctly but the connector labels are swapped – the left connector fed from the FG501A via the BNC "T" is the Delay/Duration input, not the output. In Table 5-2, Rear Connector Pin Assignments (p. 5-8), [[TM500 Series plug-in interface|pin B7]] is incorrectly labeled –33.5 V, it is the NPN pass transistor's collector.'' | * '''''Manual errata:''' In manual 070-1583-01, Fig. 4.3 Output Delay Range Check (p. 4-5), the PG 505 connections are drawn correctly but the connector labels are swapped – the left connector fed from the FG501A via the BNC "T" is the Delay/Duration input, not the output.

This must be cut/removed to float the output, in which case output common remains grounded through a 100 kΩ resistor (R545). The manual says this resistor may be removed too, but doing so will cause unspecified "degradation of performance". | ||
