HP 1813-1304 oscillator replacing 10811X

Hello, I am facing a 8663A sybthesizer containing a HP 1813-1304 instead of the well known 10811A. Two questions : 1. What are the specs, I mean is it the replacement of the 10811-60101, 102...111, 116... ? 2. Is it possible to have a schematic diagram and parts list (power is down at -10dbm). Thank you.

MSO-X 4154A is not starting from power-on

Hi, Our oscillograph InfiniiVision 4000X MSO-X 4154A was not used very long time . Now the oscillograph is not starting: after pressing power-on key all LEDs on a control panel blink twice. After that only one LED (near "Ref" button) is on. The display keep black, fan work, oscillograph does not react to pressing any button. Five times press… (Show more)

I just saw your post and I have the exact same symptom with our MSO-X 4034A, and it stays locked up also on the REF light. We were quoted nearly $4K to repair and recalibrate it by Keysight, but I'm thinking it may be something simple due to the long-term unplugging situation. Ours was also unplugged for over a year or longer. A product of this…

MSOX-4034A Boot Up Fail

I own an MSOX-4034A that has been in a lab but unplugged for over a year. Upon plugging it in, the boot-up fails to complete, stalling during the front-panel light test, with the REF light stuck "ON" and that's where it ends. The front panel light test doesn't complete and the LCD screen never shows any bootup (I believe the screen doesn't turn on… (Show more)

Hi jlaguard, I asked a bunch of people around the office, but the exact meaning of that SP designation is very elusive. The best lead we could find is this page from a national stock number search tool: which seems to indicate that this instrument had to pass the Navy's own set of quality control standards. I don't have access to those QC…

Can the E5071C measure phase margin and gain margin of DCDC converter circuit?

I found an application note describing how the E5061B can be used to measure the loop gain of DCDC converter. But I only have access to a E5071C.

PNA-X B series Phase Ref Cal issue

Hi, My company just got the B version of the PNA-X (i.e. N5247B) using the latest A.13.25.04 firmware. I'm trying to run the Phase reference calibration, using the 50GHz comb filter generator. But the issue I'm having is when it gets to step 4 to run the power calibration on Port 1. With 0 dB source attenuation setting, I should be able to read… (Show more)

Hi again, I finally found the problem! It was due to a faulty, intermittent RF coaxial cable on Port 1. That is why I was getting these erratic strange readings in different settings. Even though the cable was fairly new, I shouldn't have assumed it was good. Sorry to suspect the new B model of the PNA-X. You may mark this as closed.

[DSOX1102G][BUG] Waveform zooming yields wrong measurments

On a DSOX1102G set the following: - CH1 AC BW 10:1 - Aquire mode - High Res 1. Capture a wave form with the time frame set to <1ms (500us for example). 2. Stop data capture and measure pk-pk voltage value 3. Zoom in on the wave form (by rotating the Horizontal time frame knob) and notice the new pk-pk value of the zoomed section. Doing above… (Show more)

Fungible (to alinp) 3 days ago (Show more Show less)

So here is the theory. When you turn on high res mode the noise spikes get filtered and the waveform p-p amplitude measures 22.3mV. You then stop the acquisition and zoom in, the scope turns off high res mode as a result of the zoom but does not report that to you on screen. Since the high res is now turned off, the noise spike appear in the…

Wie ermittelt man automatisch die kleinste Amplitude? DSO-X 3024A

Ich habe den DSO-X 3024A. Es bietet zur Messung von Amplituden eine Befehl: Typ: Ampl. an. Jedoch wird hier bei verschiedene Amplitudenformen dann das größte Signal. Es gibt keinen Befehl wo die kleinste Amplitude ermittelt wird. Diese Funktionalität wird hier vermisst. Es wäre gut, wenn 2 Arten von Amplituden Messung gäbe. Einmal für das Maximum… (Show more)

How get minimum analog input voltage for an oscilloscope DSO-X3024A?

How can I find the minimum analog input voltage for an oscilloscope? I've checked the datasheet for the particular one I am using(Agilent DSO-X 3024A) and only the amplitude (maximum) voltage is listed.It would be better there are 2 amplitude, one for maximum and one for minimum amplitude values.
