Download standard MIB format if you are planning to load a MIB file into some system (OS, Zabbix, PRTG ...) or view it with a MIB browser. CSV is more suitable for analyzing and viewing OID' and other MIB objects in excel. JSON and YAML formats are usually used in programing even though some systems can use MIB in YAML format (like Logstash).
Keep in mind that standard MIB files can be successfully loaded by systems and programs only if all the required MIB's from the "Imports" section are already loaded.
The tree-like SNMP object navigator requires no explanations because it is very simple to use. And if you stumbled on this MIB from Google note that you can always go back to the home page if you need to perform another MIB or OID lookup.

Arris FFT upstream channel entry.
                 dcxFftSize 1.3.6.1.4.1.4115.1.4.5.1.1.1.1.1 unsigned32 read-write
Number of samples to be collected for FFT. Valid values are 256, 512, 1024, 2048, 4096. The FFT payload size will be the number of samples multiplied by the number of bytes per sample as determined by dcxFftOutputFormat. The duration of the FFT sample will be the number of samples divided by the sample rate as determined by dcxFftSampleRate.
                 dcxFftSampleRate 1.3.6.1.4.1.4115.1.4.5.1.1.1.1.2 integer read-write
FFT sample rate based on the input source to the FFT. The input to the FFT can be the ADC output, the ADC output followed by a down-mixer and half-band filter, the ADC output followed by a down-mixer and quarter-band filter, or the received channel's Nyquist filter output. Enumeration: 'quadrupleSymbolRate': 4, 'quarterAdcRate': 3, 'reserved8': 8, 'halfAdcRate': 2, 'adcRate': 1, 'reserved5': 5, 'reserved7': 7, 'reserved6': 6.
                 dcxFftCentreFrequency 1.3.6.1.4.1.4115.1.4.5.1.1.1.1.3 integer32 read-write
FFT centre frequency. This object is used only if dcxFftSampleRate is set to halfAdcRate or quarterAdcRate to set the down-mixer frequency.
                 dcxFftWindowing 1.3.6.1.4.1.4115.1.4.5.1.1.1.1.4 integer read-write
Set the frequency-domain windowing filter. Enumeration: 'hanning': 2, 'blackmanHarris': 5, 'blackman': 4, 'hamming': 3, 'rectangular': 1.
                 dcxFftLogAveragingTimeConstant 1.3.6.1.4.1.4115.1.4.5.1.1.1.1.5 unsigned32 read-write
Time averaging constant exponent, M. Constant is 2^M. Setting this object to zero disables averaging.
                 dcxFftOutputFormat 1.3.6.1.4.1.4115.1.4.5.1.1.1.1.6 integer read-write
FFT processor output format. Format can be i. raw complex time-domain I/Q format ii. FFT data in I/Q format iii. FFT data in power format iv. FFT data in amplitude format. The sample sizes are 4 bytes (i. - iii.) and 2 bytes (iv.) Enumeration: 'raw': 1, 'fftPower': 3, 'fftAmplitude': 4, 'fftIQ': 2.
                 dcxFftOperatingMode 1.3.6.1.4.1.4115.1.4.5.1.1.1.1.7 integer read-write
Operating mode of FFT process. Determines whether the FFT measurement takes place while no CMs are transmitting (measuring noise floor), during a CM burst, or by periodically sampling the spectrum without regard to scheduling of the upstream. Enumeration: 'baseSpectrum': 1, 'periodicSpectrum': 3, 'burstSpectrum': 2.
                 dcxFftIdleInterval 1.3.6.1.4.1.4115.1.4.5.1.1.1.1.8 unsigned32 read-write
Interval in microseconds between consecutive FFT triggers when dcxFftOperatingMode is baseSpectrum or periodicSpectrum. This object is not used if dcxFftOperatingMode is set to burstSpectrum or if dcxFftTriggerCount is 1.
                 dcxFftBurstSid 1.3.6.1.4.1.4115.1.4.5.1.1.1.1.9 unsigned32 read-write
SID on which to trigger the FFT process. This object is used only if dcxFftOperatingMode is set to burstSpectrum.
                 dcxFftBurstIUC 1.3.6.1.4.1.4115.1.4.5.1.1.1.1.10 integer read-write
IUC type on which to trigger the FFT process. This object is used only if dcxFftOperatingMode is set to burstSpectrum or periodicSpectrum. A value of 0 means trigger on any IUC type.
                 dcxFftLogicalChannel 1.3.6.1.4.1.4115.1.4.5.1.1.1.1.11 integer read-write
Logical channel on which to trigger the FFT process. This object is used only if dcxFftOperatingMode is set to periodicSpectrum. A value of -1 means trigger on any logical channel.
                 dcxFftTriggerCount 1.3.6.1.4.1.4115.1.4.5.1.1.1.1.12 unsigned32 read-write
Number of times to trigger FFT when dcxFftEnable and dcxFftApplyConfig are set to true. Set this object to zero to trigger FFT continuously.
                 dcxFftEnable 1.3.6.1.4.1.4115.1.4.5.1.1.1.1.13 truthvalue read-write
Set to true to enable FFT on this channel. Set to false to disable. Setting will take effect when dcxFftApplyConfig is set to true

Set to true to trigger an FFT process with configuration determined by the other objects in this group. An SNMP GET of this object will always return false

This object will return true if an FFT process is currently in progress (having been started by a SET to dcxFftApplyConfig) for this upstream channel. Returns false otherwise
