The '''Tektronix 504''' is a monolithic oscilloscope with a bandwidth of 450 kHz [[introduced in 1960]]. | |||
It was introduced at the same time as the [[503]], and is mechanically and electrically identical, other than the vertical amplifier. | |||
The 504 was also offered in a rack mount version, the RM504. | |||
Both scopes use the same CRTs. The CRT circuit uses a single [[5642]] to generate the - | ==Specifications== | ||

The 503 incorporates two identical phase matched amplifiers with true differential inputs to support X-Y operation, | |||
whereas the 504 contains a simple ground referenced vertical amplifier. | |||
Due to the low bandwidth and need to keep the selling price low, neither the 503 or 504 include delay lines in the vertical signal path. | |||
Both scopes use the same CRTs, the [[T5030]]. | |||
