Electronics test/lab equipment list

When not specified, this equipment was obtained for free or very cheap.

Working equipment:

Rigol DS1054Z oscilloscope, bought new for approx. 400€

Hacked to get effectively a DS1104Z
100MHz, 1Gsps, 4 channels

Hameg HM203-6 oscilloscope

20MHz, analog, 2 channels
Component tester built in, actually a curve tracer

Hameg HM8011-3 multimeter

4.5 digits
Volts ranges from 0.2V to 2000V, AC/DC
Ohms ranges from 200 to 20M
Amps ranges from 0.2mA to 10A

Hameg HM8030-3 signal generator

14mHz to 2MHz, sinus, square and triangle
Up to 10V amplitude, ±5V DC offset
FM modulation

Racal-Dana 9235 Power supply

0-35V, 0-10A lab power supply
Not upgraded, but could speak over IEEE-488 or RS-232 with the upgrade

Keithley 192 programmable multimeter

has a ~5nA leak in the input stage, leading to a drift in some cases
6.5 digits multimeter with VAC, VDC, Ohms

Keithley 6517A electrometer

Homemade triaxial cable
VFD screen is fading, may be a good idea to use over serial
Seems to drift in voltage mode, may be due to the open input circuit
6.5 digits, Down to 10aA resolution (1e-17)
Measures up to 210TΩ

Keithley 2000 Multimeter

6.5 digits multimeter but way more capable than the 192
Bought for ... not cheap

HP 3455A Multimeter

5.5 digits multimeter, not as good as the 2000 but quite the collectible
Just ended up on the pile of HP stuff

10Hz to 80MHz at 1MΩ, 525MHz at 50Ω, standard stuff
Up to 40GHz (!) from the RF connector

HP 5300B Measuring system, fitted with HP5303B Counter

80MHz at 1MΩ, 525MHz at 50Ω, again, standard
Way more manageable size than the 5352A, can run on 11-24V DC or line power

Tritron TS-1102 Frequency counter

Super compact ! Metal shell ! And bubble LED display !
Not a single result when searching for documentation, maybe homemade ?

HP 8654A Signal Generator

10-520Mhz, sine wave only
+10dBm down to -120dBm
AM and FM modulation, internal/external (pirate radio yeaaah !)
Old school tuning dial and power meter

HP 6227B Dual DC power supply

0-25V, 0-2A dual lab power supply
Can operate in tracking (series only ?) or independant mode
Right channel is a bit slow to start, may require a routine recap
Super fast shutdown !

May require fixes:

HP 3325A function synthesizer

Power button cap missing, power button itself needs replacement
VERY LOUD FAN
UNTESTED, powers up and passes all self-tests
Optional OCXO reference (not installed)
11 digits resolution
Sine wave up to 61MHz, square up to 11MHz, ramps up to 10kHz, all down to 1uHz with 1uHz resolution
Integrated sweeps

Tektronix 7704A

200MHz, 7000 series scope, 4 bays
No visible readout, maybe option 1 ?
With plugins:
- 7A12, 120MHz dual-trace amplifier
- 7A13, 100MHz differential comparator, with LED display
- 7A19, 600MHz 50Ω amplifier; most likely defective but trivial to fix
- 7A24, 400MHz 50Ω dual-trace amplifier
- 7A26, 200MHz 1MΩ dual-trace amplifier
- 7B52, 100MHz dual time base with XY support; some stuck switches
- 7B92, 500MHz dual time base
- 7D11, 50MHz digital delay
- 016-0155-00, empty slot dust cover
Usual configuration: 7A26, 7A12, 7D11, 7B92

Fluke/Philips PM5138

Waveform/modulation works fine
Output amplifier is broken, the amplitude seems stable random when changed

HP 3312A Function generator

1-10k ranges don't work, 100k and above do
Modulation works fine, and waveforms do too

HP 3438A Digital Multimeter

Need calibration for about everything
Resistance measurament is busted
AC amps is busted

Philips PM 2434 DC-Microvoltmeter

Fully analog, even the +/- display
Impressive dynamic range, from 10µV to 1kV full scale (160dB !)
Definitely needs repairs, it does a weird whine sound when plugged in, that gets louder and louder while the needle gets further right
This one scares me
