For plugins such as the 3B1 and 3B3 time bases there are issues with the blanking and intensified sweep. | 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. | 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 | 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 sn101 to 579, the +6 V 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). | Later 561's with sn580 and higher already had this change implemented.
