Re: 252 Impedance Meter
This part is available from TEGAM. We have 56 pieces in stock today. We'd probably be a relatively expensive source, but we have it and can ship when you order. Call (440) 466-6100 to talk to some one who can quote you a price, or e-mail to "sales@tegam.com". The part is specified to be a Viking/Coo...

Re: Using the 1820B Temp Regulator
There are two sources of heat to a TEGAM thermistor power sensor: The "heater" controls the temperature of a large, heavy, metal part of the housing that surrounds the input line. This control is done to reduce the effects of ambient temperature, light, and wind on the reading. It takes 2-3 hours fo...

Re: Using the 1820B Temp Regulator
Ryan; There isn't a practical reason that the 1820B heater will not do the same job as an 1830A heater. In fact, I did an experiment earlier this week with a M1110 that has a temperature sensor inside... an 1820B heated the mount to the same temperature as an 1830A to within the 0.1 C resolution of ...

Re: R1L-D1
To start with, I'm very sorry that no one noticed this question for so long. Your question is very valid. Normally, 2-wire and 4-wire specifications differ substantially, but in this case, I think that footnote 1 of the table in the manual tells all: It says, 1 Does not include test lead or contact ...

Re: CURRENT_STATE value list
I don't think that using CURRENT_STATE adds any information that you don't get from the error code: If you issue GET CURRENT_STATE CV and see 00:3, that means that the system is in normal operation (the 00 error), and that the display state is in index 3 of the list above (SM_DISPLAY_READINGS), whic...

Re: CURRENT_STATE value list
Dear Selim; The machine state values returned as the CV of CURRENT_STATE are, "SM_DEFAULT", "SM_DISPLAY_ERROR", "SM_DISPLAY_MENU", "SM_DISPLAY_READINGS", "SM_DISPLAY_SENSOR_DATA", "SM_DISPLAY_MESSAGE", "SM_DISPLAY_RANGES", "SM_DISPLAY_STANDBY", "SM_DISPLAY_CALIBRATION", "SM_DISPLAY_CONFIRMATION", "S...

Re: Info on Pragmatics 102 amplifier.
Dear Kamran; All I know is that the Pragmatic 102 is listed in old Pragmatic lists as a dual channel differential I-Q amplifier. This product was apparently obsolete already when Pragmatic sold their AWG and amplifier line to TEGAM in 2002, so the manuals, drawings and parts lists were either not tr...

Need more resolution when testing at low power
Here's the situation: You put an attenuator between the DUT port of your feed-through standard. Since you have measured the S-parameters of the attenuator, you calculate a new calibration factor for the assembled feed-thru+attenuator. With a 20 dB attenuator, the calibration factor is approximately ...

How Does the Heater in TEGAM Sensors Work?
We get questions about how the mount heater system works, how it improves reading stability, and how a user can really know if the mount is "Ready". I think the best way to illustrate an answer is to show a graph of how the mount DC power changes as mount heater voltage and current change. 1130_Heat...

Difference Between F1130, F1130A, and F1130B
F1130 was TEGAM's first 7mm / N connector "wideband" 100kHz to 18GHz thermistor mount. This was introduced before NIST alerted the community to the "RF Leakage" problem, and no F1130 was shipped new with common-mode filters. Some F1130 have been upgraded to contain filters, and these had a sticker a...
