## Command Syntax

    :MEASure:JITTerN:JITTer:TFILter:SHAPe {RECTangular | TPDecade | FPDecade | SPDecade | FORDer | SORDer}

Where N identifies one of four possible jitter/noise analyses {1:4}. For example, `JITTer4`.

## Query Syntax

    :MEASure:JITTerN:JITTer:TFILter:SHAPe?

## Description

This command specifies the TIE filter edge shape:

- `RECTangular` — The TIE filter is a brickwall filter.

- `TPDecade` — 20dB/Decade. The TIE filter edge(s) roll off at 20 dB per decade.

- `FPDecade` — 40dB/Decade. The TIE filter edge(s) roll off at 40 dB per decade.

- `SPDecade` — 60dB/Decade. The TIE filter edge(s) roll off at 60 dB per decade.

- `FORDer` — First Order. Available with the High-pass and Low-pass filter types only (see `:MEASure:JITTer:JITTer:TFILter:TYPE`), this is similar to the 20 dB per decade roll off, but the response is more curved.

- `SORDer` — Second Order. Available with the High-pass and Low-pass filter types only (see `:MEASure:JITTer:JITTer:TFILter:TYPE`), this is similar to the 40 dB per decade roll off, but the response is more curved.

  When the Second Order TIE filter edge shape is selected, you can also specify the Damping Factor using the `:MEASure:JITTer:JITTer:TFILter:DFACtor` command.
