All combinations cause the same error. Sending DIAG by itself also causes the same error. I looked at the included help built into the PNA and they also make no mention of this command. I have attached a copy of the manual I use to program it. |

That address space (57742) contains the bits to program the functionality of some of the earlier PNAs. Most of the below do NOT apply to the E835xA models. Test Set Mother Board EEPROM (0xE18E): Bit 0: #014 - loops only Bit 2: #1E1 - add source attenuation Bit 5: #016 – receiver attenuators Bit 6: #081 – reference channel transfer switch You can set or clear them as desired, but obviously they should reflect your actual hardware. You can set them via the Option Enable program; no keyword is needed for these particular options. |

I don't have any of the equipment required to perform the alignment but that didn't stop me from trying out the software. I was surprised it created two new mxcal files without the anything attached to the GPIB. Files are named mxcalfile_r4p12 & mxcalfile_r4p21. Maybe r4 is receiver #4 with S12 & 21. I have attached one of the files as a reference. Sadly, they did not make the file format available or it may have been possible to align it using equipment beyond what was originally called for. |

I guess that the way one can deal with the EEPROM to enable/disable the options that don't use via flexlm licenses is by manipulating the EEPROM bits directly. Of course, my command syntax may be wrong, and better yet, as Caesar indicated the HW may not allow the combinations. But these commands are used for something... :) No messing with Caesar! :D Test Set Mother Board EEPROM (0xE18E): Bit 0: #014 - Configurable Test Set Bit 1: #H11 - IF Access Bit 2: #1E1 - Source Step Attenuator Bit 3: #UNL - Bias Tees w/Atten Bit 4: #075 - 75-Ohm Impedance Bit 5: #016 – Receiver attenuators Bit 6: #081 – Reference channel transfer switch |
