Pre-owned, in a very good condition considering age. Minor marks, bumps and scratches (please look at photos carefully). It was cleaned, fully serviced & tested from November 2023 to February 2024 and everything is working perfectly. In the rear, 1st top left audio input wire connector was broken and replaced with a non original one. Scope tube (palmograph) is working but due to time, image is not as bright as it should (last 2 photos are: report from service and scope) and unfortunately you can't find a new one to replace it. Sold as described and as found. Please note that because particular item has very rare, difficult to find and expensive spare parts, we will not accept return of the particular item. If item is not as described and you return it, we will perform a full inspection of the item, its electrical circuit and on all the parts, as well as measurements, at the same service center that made the original service. Unfortunately this might take over a month before refunding.

Remarks
The first version
of Pioneer's classic (and rare) Test Instrument. It integrated an oscilloscope
with waveform/lissajous/FM multipath display options and combined that with
dual (V/H or L/R) level meter. The SD-1000 isn't quite as versatile in
quad-display/analysis features as the next version, SD-1100, but it's a classic
design and a very useful (and attractive) test instrument.
The unit has a
built-in frequency generator, for sweep and sine. 4 separately controllable
inputs. You can display waveforms.
The level meters
are in a Pre-Silver Aera color scheme of green/orange with a black fascia.
The SD-1000 is a
stereo display device that can synthetically observe and measure acoustic properties
such as various waves and also sound field property of a listening room.
A tuner with
multipath output can be connected and antenna alignment can be optimized more
easily.
Two large
dimension level meters can be used for power and voltage measurement as well as
VU level meter.
Input terminal
for 4-channel is also prepared.
The instrument is also equipped with a wideband frequency amplifier for a mono microphone. In this way, the sensitivity, acoustic frequency response and characteristics of the speaker system can be checked with an electret condenser microphone. The Pioneer microphone was optionally available as type Pioneer CM-01."
