5D10

Manuals – Specifications – Links – Pictures

The Tektronix 5D10 is a digital storage plug-in for 5000-series scopes. A double-wide module, it occupies the right vertical and horizontal plug-in bays.

Channel 2's V/div switch has an additional position that selects the input from a plug-in installed in the left horizontal slot.

The 5D10 does not have a data output, only analog recorder connections.

Compatibility

The 5D10 is compatible with DVST mainframes 5111/A, 5113, 5115, or 5441 operating in non-storage mode, or a 5223 digital storage mainframe operating in realtime mode. Serial number B020100 or higher is required to drive the color shutter in a 5116 mainframe.

Internals

5D10 boards (click to enlarge)

The 5D10 is a double-wide plug-in. The two halves are can be folded apart for maintenance by sliding out plastic joiner strips between them. Flat cables connect between the two halves.

Each input connects to a switchable ÷1/÷100 attenuator via a protection lamp. A gain stage with a dual FET input and an LF351 opamp implements the remaining amplification steps. Another LF351 buffers the signal into a four-diode sampler that is followed by a dual-FET source follower buffer.

The ADC is a discretely built successive-approximation design with 74LS112 J-K flip-flops in the SAR register, a current-steering DAC implemented with individual transistors and CA3080 transistor arrays, and an LM361 comparator.

Acquisition RAM is constructed using two 2114 1K×4 SRAMs.

The output board uses a DAC-08 integrated 8-bit DAC.

The 5D10 contains a discrete DC/DC converter with a MOSFET switch that produces +7.5 V, –7.5 V, and +5 V (logic) from the mainframe's +30 V rail. An LM324 quad opamp implements the voltage regulator and independent current limits for each output.

If the "SAVE" button on the 5D10 is pressed when the 5D10 is being powered up, it enters a test/adjustment mode, see photo below.
