Are these test gear worth having?

[djn]

I have a line one these and wonder if any of these would be worth having on my bench.

1. HP 3561A DYNAMIC SIGNAL ANALYZER, OPT-1, POWER

2. HP 8643A SYNTHESIZED SIGNAL GENERATOR 0.26 - 1030

3. AGILENT 6622A SYSTEM DC POWER SUPPLY 0 - 50V,

the 3561 is useful -- but dynamic range is only 80dB -- it's a great instrument for vibration analysis.

Be careful to not bid much. There is no way of knowing whether they work, and
problems are common. You can buy a guaranteed working DSA for $500 on ebay.

I have got away with a £50 second hand scope and £25 signal generator for 15 years.
One very useful tool which is free is your ears !
If it sounds bad then it is bad.

If you're doing audio work the 3561a could be fun. Doesn't work over 100KHz though. Even has its own source. The signal generator is as big as a house and would take up a lot of room. In the end you may regret that one when you're looking for space for other toys.

Watch what you spend if you're not sure of the condition. I love old HP gear but it is old gear. You never know. It could go from tool to project real quick.
