The Tektronix Type 535 is a 10*/15 MHz dual-timebase oscilloscope that accepts letter-series and 1-series plug-ins.

The 535 is functionally the same as the 30-MHz 545, but with a simpler, non-distributed vertical amplifier. Early 535s came in brown, square-cornered cabinets; in 1956 the cabinet became blue and round-cornered.

Type 535, the single-timebase Type 531, and the first four plug-ins, Types 53A, 53B, 53C, and 53D, were introduced in August 1954, advertised as "... the «convertibles» of the Tektronix line". Types 541 and 545 came out in March 1955.

In 1959, Types 531, 535, 541, and 545 were superseded by Types 531A, 535A, 541A, and 545A, which have more convenient controls. In addition, Types 531A and 535A have slightly faster (15 MHz vs. 11 MHz) vertical amplifiers.

There is also a rack-mount version, Types RM35 and RM35A.

Starting in 1963, the 535A was made with BNC connectors for the external trigger inputs. Prior to 1963, the external trigger inputs used UHF connectors. 1972 was the last year that any version of the 535 was sold. In 1973, the 54x series was still available, but nothing from the 53x series.

The first 535s had brown slide-out cases, then blue slide-out cases, and finally blue cases with pop-off sides.

* With Type A or B plug-in; 11 MHz with Type K or other fast plug-in.

Special Models

Three "special models" of 535 were made:

  • 535-S1 (sweep delay 10 microseconds to 1 second)
  • 535-S2 (sweep delay 100 microseconds to 10 seconds)
  • 535-S6 (sweep delay 1.5 microseconds to 10 seconds)

The delaying timebase on the standard non-A 535 supports delays up to 100 milliseconds. The 535-S1 supports delays up to 1 second, the 535A up to 10 seconds.

From ServiceScope No.1, October 1959:

In Type 535 and 545 the total delaying sweep time is limited to 10 ms/cm. If a total delaying sweep time in excess of 10 ms/cm is required, a K535-S1 modification kit (Tek #040-063) which gives a maximum delay sweep range of 1 s/cm. This kit is available for $40.00 in including a new front panel.

Internals

Triggering is done with a Schmitt trigger made of a 6U8 tube (in early instruments) or a 6DJ8 tube (in late instruments).

Early 535s had selenium rectifiers. The 535 has a thermal cutoff.

Power Supply

The 535's power supply provides regulated outputs of −150V, +100V, +225V, +350V, +500V as well as a +325 V unregulated output for CRT HV section.

The Power supply section is very similar to a 549. It is an all tube design using

5651 as Voltage reference
12AX7 as comparator
12B4 as -150V series pass element
6080 as +100V, +225V and +350V series pass element
12B4 as +500V series pass element
6AU6 as error amplifier for all rails
