I have never needed to use more than two, 100 Watt bulbs in parallel. Peter

I'm still searching for the problem that causes noise to enter the system when the MODE is set to CHOP and subsequently causes the traces to appear much taller/fatter. Some of the waveforms I'm

Just looking at the 2 input caps - usually 2 are used in situations where there is a 120v / 240v switch . Its setup for 120v right ? not 240v?? the 2 caps on the input should be series for voltage

Am I accurate that I likely need like 500 or 600 watts, or will less, like 200 watts be sufficient? <terrell.michael.a@...> wrote:

Found a problem with my original (Rev-A) U16 replacement board. Have a new one that works fine in the 5328B. The HP spec for the external reference input is >1V RMS (2.82V P-P) into 1K ohm, that would

You can parallel smaller lamps to get what you need. Either just wire the sockets in parallel, or add a switch to each socket to select the desired load. Then you can use it without worrying about

Everyone, thanks for the responses. I believe the unit is spec'd for a 5 amp, 250 volt fuse, when using 120 VAC to supply the unit. That means I (think) I need at least 600 watts of bulb, or am I

Does a service manual and/or schematic exist for this? unit?? At least one trimmer is bad and the screen continually blinks.? It does output DCV, and the voltages have some resemblance to voltage

I need reference oscillator assembly (standard) part no. 05315-60016 for this unit. Thanks -- Joe White KW4YW

I thought that was the case. I have been receiving yours ok. I don't get any error messages so I can't do much troubleshooting. My guess is that your ISP is blocking me, but I can't prove it. Any

Hello Hardy. I replied to your message of 4/22, but not sure it went through; that seems to be a recurring problem for us. Sorry for using list BW for this, but is only known to be working way to

Assuming normal operation for a power supply, either overvoltage or overcurrent conditions.? If you have a scope, look at the rail voltage vs the shutdown signal and see what's going on and when.

My previous idea about why the controller circuit shutdown is wrong. I measured the IN-OUTPUT of the LT1121. The input changes between 13-20V, which is more than enough headroom for a 10V output

That is a 210W power supply. You need at least 200W of lamps. [email protected]> wrote:

Hi Eric, I believe it's this cap (25V - 470uF). It's connected directly over the supply line of the LM339 and LT1121

First, you need to chose a bulb that will draw ALMOST as much current as the fuse is rated for. That way, if there's a short in the DUT (device under test), all the voltage drop will fall across the

Good Morning, Does anyone have any information about the HP 11404A Linefinder unit. I believe it is used with the HP surveying equipment (3805, 3820 etc) but I have no idea how. It looks like it would

Hi Jeremy It do have inbuilt dc block,and now john have the admin keys to use. Its straight forward to see the lic. files—also recommend to use the inbuilt usb based backup program.And as john
