===Plugin Compatibility=== | |||
The popular 60 and 70 series plug-ins were later given a “2A, 2B, 3A, or 3B” prefix. | |||
The highest bandwidth plug-ins gave a system bandwidth of 10 MHz when used in the 561A and 561B. | |||
The 561A, RM561A, 561B, and RM561B are compatible with all of the 2 and 3-series plugins that Tektronix made. The 561 and RM561 have limited compatibility with some 3-series plugins, mainly due to the CRT circuit. For plugins such as the 3B1 and 3B3 time bases there are issues with the blanking and intensified sweep. The 561A and subsequent models used a dual-secondary winding transformer in the CRT power supply, with one winding used in an intensifying pulse circuit which the original 561 lacked. Other 3-series plugins may be used in the original 561 with some modifications. For example, to use a 3A74 4-channel vertical plugin in a 561 sn101to579, the +6V unregulated supply needs to be disconnected from both plugin connectors (pin 18). Later 561's with sn580 and higher already had this change implemented. More information regarding the use of 3-series plugins and the required modifications (if available) can be found in the Tektronix 561 Instrument Reference Book (IRB). | |||
