Page 8: 4 System Functions And Features
Flann Microwave Model 625 4 SYSTEM FUNCTIONS AND FEATURES 4.1 POWER‐UP PROCEDURE When the instrument is connected to a PoE‐compatible network, it resets to the 60 dB reference position. This action may be disabled if required, but the instrument must be reset as soon as possible to establish the correct reference alignment. Refer to the ‘PWR_ON_RST’ and ‘RESET_INST’ commands in section 5.2. The instrument is supplied with ‘PWR_ON_RST’ set to ON. The instrument can be programmed to return to the last setting prior to power being removed. Refer to the ‘HOLD_SET’ command. 4.2 SETTING ATTENUATION The instrument can be set to attenuation values in the range 0.0 dB to 60.0 dB using the VALUE_SET command. The smallest incremental value depends on the absolute attenuation: 0.01 dB (up to 20dB ... -
Page 9: Instrument Errors
Flann Microwave Model 625 When the high attenuation setting is active, this enables a coarse attenuation setting of up to 90 dB. Refer to the ‘HIGH_ATTEN’ command. The attenuation accuracy beyond 60 dB is not guaranteed. The front panel display colours are inverted when the attenuation is set to a value greater than 60 dB. 4.3 INSTRUMENT ERRORS Instrument errors can be identified by interrogating the Status Byte (see information for the ‘INST_STAT?’ in section 5.2, and refer to Table 3). 4.4 FIRMWARE UPGRADES Users will be able to upgrade to the latest version of the Model 625 firmware over the Ethernet interface by following the instructions given on the Flann Microwave Ltd website, www.flann.com. A copy of the latest issue of this manual will also be available for download. ... -

Flann Microwave Model 625 5 ETHERNET COMMAND STRUCTURE This section details the commands available and the valid operands that may be used with them. 5.1 NOTATION Upper case bold characters represent the (program code) commands, which must appear exactly as listed. Program code commands are not case sensitive, i.e. upper and lower case characters are accepted. The input buffer is 50 bytes maximum. Characters enclosed in the {} brackets are qualifiers attached to the basic command. A space may be inserted between it and basic command, e.g. {ON|OFF} shows that either ON or OFF can be attached to the root mnemonic. For example, the ‘PWR_ON_RST’ command has three possible applications: 1. PWR_ON_RST ON ‐ Switch on the Power‐on Reset 2. PWR_ON_RST OFF ... - Page 11 Flann Microwave Model 625 STORE_VAL value Sets the stored setting to value Query: Valid, returns stored setting Value 0 to 60.0 (dB) REC_SETTING Sets the instrument to the stored setting (dB) Query: Invalid HIGH_ATTEN {ON|OFF} Sets the high attenuation feature on or off Query: Valid, returns 1 for on, or 0 for off The front panel display colours are inverted when the attenuation is set to a value greater than 60 dB. HOLD_SET {ON|OFF} Returns the microwave instruments to the position when power was removed Query: Valid, returns 1 for on, or 0 for off PWR_ON_RST {ON|OFF} Enables or disables the Power‐on reset Query: Valid, returns 1 for on, or 0 for off RESET_INST Re‐synchronise the instrument by driving to the reference position of 60.0 dB.

Page 14: 6 Care Of The Instrument
Model 625 6 CARE OF THE INSTRUMENT Internally, the 625 System Attenuator is a delicate instrument. When the waveguide ports are not connected, it is recommended that flange covers (such as supplied with the instrument) are fitted. This will help prevent inadvertent damage to the flange surfaces and internal vanes, and prevent dust from entering the waveguide structure. ... - Page 15 Flann M Microwave Mod del 625 7 REG GULATO RY INFOR RMATIO 7.1 D ECLARATI ION OF CO ONFORMI ITY Model 62 25 Versio on 1.2 June 20 Page 15 of 16 ...
